THIS IS HOW UNITS LOOK LIKE: NBT NBT- EVO NBT-ENTRY

OK, sorry we didn’t have time to update our site lately due to very busy CCC/CIC repairs, seriously we barely can keep up with it, even though we don’t need that many repairs, but since we offer these services, it would not have been right to go on 6 months vacation and let everyone be pissed with their faulty units, yes, imagine we are the only one small company, who can repair these complex units and code them on the bench to match your VIN, so you don’t have to see any dealers!

Anyways back to the main topic NBT- Next Big Thing, this is how BMW decided with the new name for new generation navigation system in 2013. Yes its really new and compared to CIC unit is a huge breakthrough everywhere: software, hardware, storage, security etc etc.

NBT WAS UPDATED TO NBT2 EVO IN 2016, BASICALLY BMW UPDATES NAVI UNITS EVERY 3 YEARS. NBT2 SUPPORTS APPLE CARPLAY AND HAS BETTER HARDWARE INCLUDING EXTRA RAM 4GB.

So lets talk about main NBT features:

  • Now we have 2 computer systems in one: QNX (Linux) Jacinto CPU running all code for communication between your car and HU NBT unit +INTEL X86 CPU and NVIDIA running multimedia (CIC unit had only one 700MHZ risk CPU running everything). This is how we are getting very quick smooth HD graphics independent from QNX JACINTO CPU. So basically there are 2 laptops in one unit communication with each other using QNET high speed network!
  • NBT now contains Bluetooth and WiFi modules inside, all you need is ATM telephone module!!! remember in older units everything was separate on the MOST bus, which was cumbersome and finding faulty unit was a hassle! Now you only have TOP HIFI logic7 amp sitting on the MOST bus, and only if your car was equipped with logic 7 amplifier, so troubleshooting is much easier now and in case of amp failure you get “NO WARNING TONES” message, telling you MOST bus has issues.
  • NBT comes with 300$ 200GB TOSHIBA endurostar automotive HDD and they go bad. HDD is now locked to NBT unit individually, meaning you can not read HDD or replace it without HDD security installed. YES it is not easy like it was used to be with CIC units where HDD would fit from any CIC unit. So they sort of protected personal data and at the same time made it really hard just to replace HDD, so they want you you replace entire HU NBT if HDD failed.
  • NBT is much better built unit, than CIC unit and finally it comes with good cooling system and has vent holes for better ventilation. All in all its very nice inside with highest quality!!! Please don’t think it doesn’t cost much to produce these units for HK BMW. I’m sure they spent 100+ millions on development alone, and parts are very expensive too, so I roughly I would say it costs at least 600-700$ to build this unit for Harman Kardon. Yes its very complex and the most complicated unit in your car, YES THE MOST COMPLICATED UNIT in your car, all other nits are quite simple vs HU NBT, for example DME or engine module has only one CPU controlling injectors and tons of different sensors, but its not even close to complexity of your NBT unit
  • NBT contains FSC codes for NAVI, MAPS, VOICE APPS and they are VIN coded, so if you think of buying a cheap unit from junk yard, think twice: you will get a unit which will not work in your car properly-lots of functions and options will not match your car (unless you got lucky and donor car had same options like yours). For example PDC, cameras and so on might not work, but its not the worst part, the worst part you will not be able to use navigation or voice control or sat radio or BMW apps. YOU NEED TO CODE YOUR NBT UNIT AND UPLOAD CORRECT FSC CODES (ISSUED BY BMW SERVER) IN ORDER TO RESTORE FULLY FUNCTIONAL NBT UNIT. WHEN WE REPAIR NBT NITS WE UPLOAD ALL CODES AND EVEN TURN OF BMW APPS CODE IF REQUESTED AND CODE IT TO YOUR VIN (WE BUILT SPECIAL APP TO AUTOMATICALLY EMULATE YOUR CAR ON THE BENCH PRETTY MUCH)
  • NBT DOES NOT SUPPORT SSD DRIVES UNLIKE NBT 2 EVO. BE CAREFUL NBT EVO HAS COMPNENT PROTECTION MODE, MEANING IT WILL DISABLE OR BRICK YOUR NBT EVO YUNIT IF YOU CONNECTED USED NBT UNIT TO YOUR CAR WITH DIFFERENT VIN. YOU CAN ONLY CONNECT IT WITH EMULATOR TO PREVENT IT, WE CAN PROPERLY UNLOCK IF IT HAPPENED! NON EVO DOES NOT HAVE COMPONENT PROTECTION SO YOU CAN CONNECT ANY UNIT, IT WONT WORK BUT AT LEAST IT WONT BRICK IT.
  • All in all nbt unit is very nice complicated masterpiece from HK BMW, AND YOU ASKED FOR IT!!! WE ALL WANT HIGHLY SOPHISTICATED TOYS IN YOUR CARS, OTHERWISE YOU CAN NOT COMPETE WITH OTHERS, SO DON’T BE SURPRISED WHEN DEALER ASKS 2500$ TO REPLACE YOUR UNIT!!!!!

NBT-ENTRY WITH 6” SCREEN UNITS WITHOUT NAVI OPTION 609

  • NBT-ENTRY 2012-2016 WAS INSTALLED IN CARS WITHOUT NAVI 609 OPTION
  • ITS SIMILAR ARCHITECTURE BUT HAS ONLY ONE CPU RUNNING QNX
  • THEY DO FAIL, AND 99% ITS STUCK BMW LOGO REBOOTING
  • UNITS MUST BE CODED WITH FSC UPLOADED
  • WE DO REPAIR THEM AS WELL

NOW LETS TALK ABOUT NBT, NBT EVO, NBT ENTRY REPAIRS AND MAIN SYMPTOMS!

NBT ENTRY SINGLE DIN 2012-2015, they usually fail like this:

-BMW LOGO stays on the screen

NBT ENTRY UNIT FAILED, BMW LOGO STUCK AND REBOOTING…

-rebooting and other abnormalities

cheapest price online is $1400 and you will have to program it to your VIN, which is not very easy, while after repair it contains all you fsc data (sat radio) and coding already, so our $585 is pretty low…. so if you buy used or new, you will lose Satellite radio and other things, remember they all look the same, but part number matters: some support rear camera, some don’t, some support fiber optics, some don’t. So the best option is our inexpensive repair with 1 year WARRANTY!

BMW CIC and ComBox retrofit DIY

What it takes to retrofit CIC and COMBOX to your E90 E91 E92 E93 E60 E61

E63 E64 E87 E65 E66 ETC.

So you decided to retrofit CIC unit instead of CCC or MASK unit. Well its a good idea because with CIC you will be getting quite modern setup even by today 2017 standards:

  • LED High Definition screen

  • 600 MHZ processor (200mhz max CCC)

  • HDD for maps and music and other things

  • DVD video (can be setup in motion as well)

  • HD radio built in and SAT tuner (latest CIC after 2010)

  • Great navigation maps with current support

  • Better reliability vs CCC

  • COMBOX support for BT streaming with full control (albums, tracks, etc)

  • Backup camera support with extra video module

  • Internet support. Yes actual internet so you can really browse pages

As you can see with CIC navi unit, you will be getting pretty much current standards of multimedia in your car for a luxury car. So is it worth it? Absolutely. I will try to be as short as possible, so not to scare you from doing it.

IF YOU NEED HELP WITH CIC RETROFIT OR NEED ACTUAL RETROFIT KIT, WE CAN ALWAYS HELP. PLEASE CALL (415)-323-3412 OR BETTER EMAIL WITH ALL YOUR CAR’S INFO HERE LOGIC7REPAIR@GMAIL.COM

So you will need to perform next simple steps to get CIC working:

  1. Remove your current CCC module, Screen and Idrive controller (optional). CCC Idrive controller is better quality and much stronger vs newer one and looks nicer and does not squeak and lasts forever, though newer one has lots of shortcuts (not very important) and you will need to buy extra bezel and spend extra some hours.

E60 E90 E91 E92 E93 CCC HEAD UNIT Removal Instructions:

  1. Remove female pins from CCC power connector and repin them into CIC screen connector, just 4 wires.connector, just 4 wires. 

  2. Install CIC screen and the head unit, run new video LVDS cable from the screen and connect it to LVDS connector (head unit pink color 1)

  3. Get it coded and NAVI activated or if you prefer you can use CAN filer module (not recommended). CIC will not let you use navigation menu otherwise (by default CIC only works with one car vin number and of course it will not match your car).

  4. Update navigation maps using your usb port you connected to CIC head unit (not the combox USB!). Buy FSC codes from dealer (150$) or get it generated online (20$ only) or if you buy it from us it will be activated and updated already without any filters.

To get COMBOX module working you will need:

  • Remove your current TCU and/or MULF (if you have it). Located in the trunk in the spare tire area, convertible E64 has it behind rear left (driver side) backrest.

  • Remove pins from 54 pin TCU module connector and repin them into 26 pin 61136913626 Combox connector according to this diagram (click to enlarge) :

MOST Connector needs no modification.

  • Install MOST jumper into the MULF MOST connector, because you will not need it anymore and you can not have open MOST connector siting there (loop will be broken otherwise)
  •  Install antenna connectors (2 GSM and 1 Bluetooth antenna). You might need to cut plastic connectors groves on the combox unit to fit your older TCU antenna FAKRA connectors.
  •  Run USB and AUX cable into center console (optional).
  •  Code CIC unit and COMBOX and done!

BMW F01/F02/F07/F25 AMPT70 AMPH1 AMPTLR13 LOGIC 7 AMPLIFIER REPAIR 2007-2019

$550 Any BMW fiber optic amplifier 2002-2019 except B&O amplifier.

In this article we are going to describe another next generation LOGIC 7 amplifier, which can be found on lots of BMW vehicles: F01/F02/F07/F04/E71/e70/e64/e64 and others, usually it says on it : AMPT70 (E70/E92/E63/E64) or AMPH07LR02 (F01/02 type)

img_4020

Even though they have lots of different part numbers, but in reality this is the same amplifier, the only difference is coding, so based on the type of vehicle, this amplifier is coded to support different speaker setups and crossover settings.  THIS IS HOW IT LOOKS LIKE:

fullsizerender_1

This amplifier works the same way as first generation logic 7 amps was:

real_oem

Head unit or CIC sends digital sound data over fibre optic network called MOST, then amplifier receives it, converts to analogue signal and powers up 9 channels in your car and you can hear high end quality sound without any noise or very low noise compared to standard analogue amps.

This amplifier compared to previous LOGIC 7 generation has lots of advantages:

  • CLASS D
  • MORE POWER OUTPUT 600W
  • BETTER QUALITY BUILT BY LEAR
  • NEWER MORE RELIABLE CHIPS USED
  • SOUND QUALITY IS MUCH HIGHER
  • LESS POWER CONSUMPTION
  • LESS HEAT PRODUCED

Main problems with this amplifier:

  • NO SOUND AT ALL, SUDDEN LOSS OF SOUND
  • CRACKLING SPEAKERS
  • NO COMMUNICATION WITH THE AMP
  • LOW VOLUME AND WEAK POWER
  • NO DOOR CHIMES, NO SOUNDS AT ALL

SO GOOD NEWS WE CAN REPAIR THESE AMPLIFIERS WITH A GREAT SUCCESS.  Basically if your amp looks like the one on the pictures, we can fix it. These amps you’ll find in these BMW models:X5, x6, z4, m3, f01, f02, e92, e64, e63 and may be others. Part number is not very important, because we repair them all as long as they look similar to the pictures here. On older BMW it was called individual amplifier, so higher level than just logic 7 options, usually found on top vehicles, like M3, M5, X5M, M6 and others.


  Standard symptoms:

-no sound at all

-crackling speakers or sub woofers

-no communication

-other audio issues

After repair you don’t need any coding, it will be plug and play.

Frequently Asked Questions:

1. HOW DOES IT WORK?

-SIMPLE. YOU REMOVE YOUR AMPLIFIER AND SEND (FITS REALLY WELL INTO USPS FLAT RATE PRIORITY BOX 12$) IT TO US AT THE ADDRESS BELOW. IT TAKES 1-2 DAYS PLUS SHIPPING 2-3 DAYS MAX.

(415)323-3412

2. HOW DO I KNOW IF MY AMP IS BAD?

-BASED ON SYMPTOMS AND DIAGNOSTICS. USUALLY NO SOUND MEANS AMP FAILED OR IF SPEAKERS DON’T SOUND RIGHT. IF WE GET YOUR AMP AND IT APPEARS ITS IN GOOD SHAPE WE ONLY CHARGE 50$ DIAGNOSTICS FEE.

3. DO YOU TEST THEM?

-YES WE STRESS TEST ALL THE AMPS PRIOR TO SENDING BACK

4.WILL IT LAST?

-YES IT SHOULD LAST SIMILAR TO BRAND NEW AMP, BECAUSE WE INSTALL ORIGINAL OEM PARTS. CHECK OUR REVIEWS, WE REPAIRED 1800+ AMPS SINCE 2011.

Also we install more powerful power chips, so it can sustain higher current ratings.

5. I HAVE DIFFERENT SYMPTOMS, CAN I CALL?

-IF YOU DIDN’T FIND ANSWERS HERE, CALL OR EMAIL HERE

(346) 336-9333

6. How does the warranty work??

-simple. If something happens to the amp, but without physical damage or water damage, you can send it back, all we need to know is eBay or PayPal transaction id, this is how we know all the info: when warranty starts, model of the amp and serial number and what has been done to it.

7. Is it safe for my car?

-absolutely. We install oem parts, so there is no difference made to the amp internals.

8. Is it legitimate business?

-yes it is, we’ve been around since 2009 fixing amps. You are fully protected by PayPal and eBay policy. Which means you can always get your money back if something didn’t work out. So far we repaired 1900+ amps, we work with dealers all over the world but mostly within USA.

9. Why is it so much to repair it?

-well, this amp is fully digital and has nothing to do with old school amps you can buy new for 100$. Parts are expensive and we use expensive equipment to work on them, plus we provide 1 year warranty, which costs us a lot as well. In some cases amps come water damaged, which makes repair way more complex or not repairable!!

NOTE: additional fee might apply in abnormal cases like water damage or burnt pcb

10. Why would I pay 550$ if I can find used amp for 300-400$??

– well, for a few good reasons:

A) we install new oem parts which usually go bad on these amps with years, so it should last longer than used amp more likely it’ll last like brand new one.

B) this amplifier has your car VIN number coded. so you will not need any coding, because you will get your amplifier back which was coded to your car from factory. Coding is not that simple, so buying used amp will not be plug and play. Bmw dealer will not program used amp or any other used part to your car, only new parts will be installed and coded at the dealer, which means it might cost you up to 2000$ to install a new amp correctly. In our case you DON’T NEED TO SEE ANYBODY, which means you will spend only 550$ period.

BMW E65, E66, E60, E63, E90, E92, E93, E64, E87, E53, E70 AUX PORT MOD MODIFICATION

Yes, it is very annoying, that BMW decided not to install aux port by default in our vehicles before 2007. In this post let’s find out what you need to get for AUX port in your bimmer.

E65 BMW 750I, 750LI, 760LI, 745I, 745LI, 730I, 730D ETC.

If your car is pre 2007, and you don’t have aux port in your idrive and neither you have aux port in your glove box- you are not in very good shape. To say the least its the hardest bmw body type if you decided you need aux port! Why?  Because ask unit cd player and pretty much all multimedia modules in this car are digital, and there is no analogue signals anymore, and aux port signal is analogue, so common sense tells you need to convert it to digital bmw e65 signal in order to get sound from your sound system, doesn’t sound easy at all to say the least.

So here are the options:

  1. BMW E65 FACTORY OEM AUX PORT INSTALLATION.  DO NOT EVEN THINK OF BUYING BMW OEM AUX CORD JUST BECAUSE SOMEONE SAID ITS SO SIMPLE: BUY THE CORD 5-75$ CONNECT OT THE BACK OF YOUR ASK UNIT AND DONE??? REALLY?  YES, CORD WILL FIT IN THERE AND THAT’S IT HERE- YOU WILL NOT GET ANYTHING WORKING APART FROM THAT GOOD SIDE YOU HAVE USELESS AUX PORT IN YOUR CAR. WELL, HERE IS WHAT YOU NEED:
    1. IF YOUR CAR IS PREFACE LIFTED 2002-2005  BMW 745I, 745LI, 760LI, 730I, 730D, THEN YOU NEED NEWER TYPE MMI SCREEN FROM 2006-2008 MODELS PLUS NEWER 2007-2008 ASK UNIT CD PLAYER. AND AFTER THAT YOU HAVE TO CODE BOTH TO YOUR CAR USING NCS EXPERT BMW PROGRAM TO ENABLE AUX INPUT IN MMI SCREEN (IF SCREEN CAME FROM 2006 CAR) AND CODE ASK UNIT TO WORK WITH YOUR TUNER AND OTHER MODULES. WHY? BECAUSE EVERY CAR  HAS DIFFERENT OPTIONS AND FOR EXAMPLE RADIO TUNER WILL NOT WORK WITH NEWER ASK UNIT IF NOT REPROGRAMMED OR RECODED, ALSO SOME CARS WERE EQUIPPED WITH L7 TOP HIFI SYSTEM VS STANDARD HIFI SYSTEM, THAT’S WHY THOSE MODULES HAVE TO BE CODED. AND ONLY AFTER ALL THESE PROCEDURES YOU CAN BUY AUX BMW CORD AND IT WILL WORK! ALSO YOU WILL NEED FACELIFTED WOODEN TRIM, BC YOUR ORIGINAL WILL NOT FIT ANYMORE.
    2. IF YOUR CAR IS FACELIFTED 2006 BMW 750I, 750LI, 760LI, 740D, YOU ARE IN BETTER POSITION. YOU WILL ONLY NEED NEWER ASK UNIT 2007+, BC EVEN THOUGH THEY LOOK THE SAME, HARDWARE INSIDE IS SLIGHTLY DIFFERENT AND ONLY LATER 2006 (WEEK 30 AND UP)+ MODELS WILL WORK WITH AUX UNIT AND CODING MMI SCREEN TO ACCEPT AUX INPUT, THEN YOU WILL GET AUX IN THE MENU AND EASY WAY TO CHECK IF ASK UNIT SUPPORTS AUX IS TO SEE IF IT RETURNS AUX LEVEL AFTER YOU CHOSE AUX IN THE MENU. OLDER ASK UNITS WILL NOT RETURN THAT LEVEL SUB MENU.

2. NON OEM AUX PORT CAN ONLY BE INSTALLED VIA RADIO TUNER MODULE, YOU WILL GET CLEAR SOUND, AND IT WILL OVERRIDE ANY RADIO STATION. VERY SIMPLE, YOU PLUG YOUR PHONE AND YOU WILL GET CD QUALITY SOUND. IT WILL ONLY WORK IF YOU DON’T HAVE HD RADIO MODULE. WILL WORK WITH ANY E65 2002-2008.  THIS IS TOTALLY DIFFERENT COMPARED TO LOW QUALITY RADIO TRANSMITTERS MODS. IT HAS NOTHING TO DO WITH FM/AM, IT WILL OVERRIDE SOUND SOURCE. WORKS VERY GOOD WITH APPLE DEVICES. IF YOU NEED HELP WITH AUXILIARY PORT INSTALLATION YOU CAN EMAIL FOR DETAILS.

ALL OTHER SERIES ARE MUCH EASIER. E60, E90, E63, E64, E92, E93, E87, E53, E70 WILL ONLY NEED AUX PORT ENABLED VIA NCS CODING AND BUYING A CABLE.

Smoking white from tailpipe?? N62, N72 family engines applies to any V8, V12 from 2002 AND UP.

Smoking white from tailpipe?? N62, N72 family engines applies to any V8, V12 from 2002 AND UP.

smok valve seals

So most likely if you own bmw with N62 or N73 engine, most likely you have oil consumption or you noticed your car smokes white after prolonged sitting and idling??? Well this is the worst and very common problem with these engines. Do not listen to any fairy tales and accept it:

YOU NEED NEW VALVE SEALS! AND IT ALSO CAUSES CLOGGED AIR PORTS ON N62B44

Nothing will help and don’t waste your time and money:

-don’t even try thicker oils, it won’t help and is very bad for vanos lines

-don’t think any seafoming can help

You can replace CCV or mushroom valves on the valve covers. If they are cracked, you will get check engine light or simply it will introduce oil fumes into combustion camera. But here is the catch:

ccv

even if CCV is bad and torn completely, there is not much oil in the fumes to produce that much smoke anyways, even if you connect crankcase line directly into intake manifold (this is how it was connected in old cars anyways), you will not get much or any noticeable white smoke if compression is good, but it will affect oil consumption for sure.

But when valve seals are bad, you will definitely introduce lots of oil into the combustion camera, because it leaks right on the piston, compared to CCV, when there is time to mix oil fumes with intake air.

this what you need:

valveseals

FAILURE TO REPLACE VALVE SEALS WILL CAUSE:

-CATALYTHIC CONVERTERS FAILURE SOONER OR LATER

-RESTRICTED AIR FLOW FOR SECONADRY INJECTION PORTS ON 745LI, 645I, 545I, 745I

-WILL DAMAGE SPARK PLUGS

-WILL MAKE YOUR COMBUSTION CAMERA DIRTY, CAUSING ENEVEN IDLE AND POWER LOSS

-DRIVING WITH LOW OIL LEVEL WILL DAMAGE THE ENGINE

-WILL CLOG MUFFLERS AS WELL

So long story short you need valve seal job, which is expensive even at small shops 1500$-3000$ or 8000-9000$ at BMW dealerships!!!!! Good news is new valve seals were updated and will last for long.

My GOOD recommendations:

-YOU CAN DO IT WITHOUT REMOVING HEADS

-AVOID AGA MAGICAL TOOL: IT IS MUCH FASTER AND EASIER TO REMOVE CAMS AND DO IT RIGHT.

-ALWAYS REPLACE UPPER TIMING CHAIN COVER GASKETS ALONG WITH NEW VALVE COVER GASKETS

-REPLACE CHAIN TENSIONERS IN THE HEADS, BUT I ALSO RECOMMEND NEW CHAIN GUIDES, BECAUSE THEY DO WEAR OUT AND CAUSE UNEVEN IDLE AND POWER LOSS.

-INSTALL NEW CCV AND CLEAN CCV LINES EVERY 60KMLS

-DO NOT EVEN THINK ABOUT USED ENGINE!!! IT COULD AS BAD AS YOURS, BECAUSE RUBBER VALVE SEALS DO AGE WITH YEARS OF SITTING BADLY.

ALL VEHICLES EQUIPPED WITH N62 ENGINES WILL EXPERINCE THIS PROBLEM SOONER OR LATER! IT CAN HAPPEN EVEN TO LOW MILES CARS, EVEN 40-60KMLS, SO WHEN YOU BUY N62 CAR

Battery replacement BMW e65 745i, 745Li, 750i, 750Li, 760Li, 730D, 740D, 730i, 735LI, common mistakes

Applies to any BMW with power module:

e90, e60, e70, F01, F02, F30 etc

So you got a “recharge battery’ warning, and you went to AutoZone or any other store and bought new battery. You installed it, then you probably were told to register it, or some mechanic registered it for you.

You think everything is good now, right?? But battery warning still comes back and some smart mechanic or independent shop tells you its okay as long as battery is new and registered!

So here is the story:

One 2003 BMW 745li with very low miles came over with ABS module errors and with battery discharge warning. Well, he replaced the battery and it was “professionally registered”. But not only problems still there, but now it actually creates lots of faults on the top! Plus his alternator seized! Coincidence?? So lets see:

BMW e65 before 2004 were equipped with 110ah standard lead acid battery.

After 2004 they introduced new standard, which is 90ah AGM battery (which is great battery if maintained well).

So not only type is different, but capacity is lower!!!

What happens when today you buy 90AGM battery (they don’t sell older 110ah battery for these cars) and install it into the vehicle which has highly sophisticated power module, which knows battery type and capacity??

Quite simple:

it will still think you have 110ah lead acid old battery and it will constantly try to charge it to get it to fully charged state!!! And it will not ever happen, but will destroy your new battery and will put lots of stress on alternator plus you might get various faults in different modules!

OLD 110ah LEAD ACID BATTERY setting:

CBS_SCEN_10H
    nicht_aktiv
CC_15_EIN
    wert_01
BATTERIE_KAPAZITAET
    110ah
ERKENNE_SBE1_HI_RE

NEW 90AGM SETTING

BATTERIE_KAPAZITAET
    90ah
ERKENNE_SBE1_HI_RE

or you can use BMW progman, which will do it automatically, but i prefer NCS instead: quick&easy&safe

That’s why BMW dealership will charge you more to reprogram your vehicle so it supports new battery type. This is what lots of mechanics and shops don’t know about or simply ignore it!!! Why?? because they don’t want to learn anything and interested in quick and easy money.

So basically you are supposed to check what power module says, but if your car is 2004+, most likely it came with 90AGM and all you need to do is to register it. There are few options here:

BMW INPA, ISTA, aftermarket tools can run it too, but only NCSEXPERT or PROGMAN can reprogram power module so it supports 90AGM.

AND YES YOU HAVE TO REGISTER NEW BATTERY, BECAUSE POWER MODULE CONSTANTLY CHECKS THE BATTTERY CAPACITY AND WITH AGE, BATTERY GETS WEAKER AND THEREFORE IT APPLIES LESS CURRENT TO FULLY CHARGE IT. SO NOT REGISTERING NEW BATTERY WILL MAKE POWER MODULE THINK, YOU HAVE STILL OLD WEAK BATTERY AND IT WILL NOT TRY TO FULLY CHARGE IT (I’M NOT GOING DEEPLY INTO DIFFERENT SPECS IT CHECKS AND RUNS WHILE YOU DRIVING YOUR CAR), BUT BOTTOM LINE YOU HAVE TO REGISTER IT AND IF YOUR CAR IS OLDER MODEL, YOU AVE TO MAKE SURE POWER MODULE ACCEPTS 90AGM.

HYDRAULIC TRUNK LIFT SAGA, MAIN ISSUES!

In this post i will describe standard problems and the ways to fix it and also the ways to retrofit it back to simple trunk shocks.

trunk_hydro

Premium option S316A for e65/66 was hydraulic trunk lift.  Yes its very comfortable and convenient, but with years these nice options give  more headaches, than luxury feeling. This Option includes:

-electro-hydraulic pump (located in the rear right panel) (8) -rarely just low on fluid due to leaks

-hydraulic piston or actuator, which lifts the trunk (3)- fails often, leaks onto NAVI unit

-Trunk lid shocks (23) -fails often

-electronic module (12) -rarely fails

And what fails? Everything, except for the pump (it has safety prevention valve).

 TRUNK LID SHOCKS FAILURE:

So if your trunk lid still opens after you press the button (remote, interior, trunk button), but it wont stay open or barely stays open especially on the hill

shocks_trunk

– YOU NEED NEW TRUNK LID SHOCKS (23), they got upgraded with silver coils vs old black ones which always fail.  NEW upgraded P/n: 51247201461. So even if your old ones are still working i strongly recommend newer springs, because it will help to reduce stress from hydraulic cylinder as well.

  Hydraulic Cylinder Leak:

Well, this is the worst and most expensive…. So if you press the button and nothing happens or you can hear the pump is trying to lift the lid but it shuts down right away, it means 2 things:

-Hydraulic fluid is low and therefore it stops the pump from failure. Sometimes BMW says you can loose some fluid over the time due to evaporation, aging etc…. but in my experience it means Cylinder leak. You can add some fluid into the pump on the left panel, but most likely it will leak out soon.

-Cylinder leak. In this case it explains where the sticky red fluid leaked and created mess in your left rear panel,  usually you see SVS,  NAVI unit covered in oil.

trunk_hydro

Options? Well you need new hydraulic cylinder kit p/n: 51247202868, which is quite expensive ~300$.  Plus you need new shocks 160-180$, 500$ in parts!! Lots of hassle to install it as well.

OR IF YOU ARE TIRED OF THIS (300$+160$(SHOCKS))AND WANT JUST A SIMPLE TRUNK OPTION, I RECOMMEND YOU FOLLOWING STANDARD TRUNK LID RETROFIT:

-you need to remove trunk shocks (use sharp pick tool to remove shock lock)

-disconnect  hydraulic cylinder and remove it including lines or simply move it out of the way.

-disconnect hydraulic pump electric connector or disconnect hydraulic trunk HKL module.  You can code it out using NCS, but not necessary.

-buy and install standard shocks 80$ each p/n: 51247201463

-DONE! Enjoy standard hassle free trunk lid with soft close feature. I know its not that luxury, but 500$ still in your pocket and you should be happy, bc no more worries it will leak again and flood your expensive modules. BMW says not to leave your car in the open sun, bc it makes things worse for hydarulic cylinder causing premature failure.

 

 

This article is about most common BMW cooling system faults and how to diagnose and repair it.

Well, to start we need to know what perfect temperature specs for this V8 V12engine.

When car is fully warmed up and idling for 10 minutes you should see these numbers:

Upper Hose temperature-103-105C

n62b44_tstat_open_oem

note: Lower hose should be within 60-70C, this is very important because it indicates proper cooling system function. Lower hose or coolant output readings should be within 60-70C with open tstat.

very common mistake when mechanic thinks he bled the system right, but he doesn’t know the heater control valve is clogged and there is no way to bleed the air out and lower hose stays COLD, even auxiliary water pump fails because of this.

This screenshot shows proper transmission temperatures, when cooling system is fully functional and sealed:

6hp26_temps

 

NOTE: Some cars have cold firmware which opens up thermostat earlier therefore engine running temps are lower.

ALWAYS REPLACE RADIATOR CAP EVERY 5 YEARS, IT DOESNT LAST FOREVER!

If temps stay at 105-110C, it definitively means you have an airlock, which causing overheating and lower hose running cold.

This engine has self bleeding system, but it only works if cooling system is in great shape!

So most common problem you cannot bleed the air out is HEATER CONTROL VALVE, which always goes bad after 5-7 years or even earlier. Its very easy to replace and costs around 140$. Usually rubber valves crack and deteriorate clogging the valve so you cannot bleed the air out, moreover it clogs heater core, which is a real pain to replace. So remove the valve and at least inspect it:

-it should be clean inside and valves are open without 12V applied and easy to blow air through, in other words it should not have any restriction, but word of advice-REPLACE it, don’t wait, and it will also improve heat cabin.

 

LEAKS:

-Front seal aka weep hole problem can be easily diagnosed checking weep hole on the timing cover

Can be easily fixed with aftermarket solutions or with simple aluminum+RTV solution, which actually works pretty good.

-Valley pan gasket leak. You need to remove intake to replace it. Be careful not to damage knock sensor which is very common.

-Rear cover plate. Hardest point here-you need to remove transmission for that

 

Other leaks include lower hose sensor leak and hoses also get old and is a good idea to replace them every 5 years. Also Vent hose connected to the heads near throttle body goes bad every 5years or 80-100kmls

 

Always pressure test your cooling system- you cannot rely on visible findings saying there is no leaks.

You cannot see 30% cooling hoses located in the rear of your engine.

MAKE SURE YOU ALWAYS BLEED AIR OUT FROM COOLING SYSTEM EVERY TIME YOU WORKED ON IT:

-FILL COOLANT TANK TO FULL WITH BMW COOLANT, LEAVE CAP OPEN.

-TURN ON IGNITION (DONT START ENGINE YET) AND SET HEATER TO 90F WITH LOW FAN SPEED. MAKE SURE AUXILLARY PUMP IS RUNNING-YOU SHOULD HEAR IT ON THE DRIVER SIDE, LET IT RUN FOR 5 MINS

-START THE ENGINE AND LET IT RUN FOR 5 MINS, CLOSE THE RADIATOR CAP

-DRIVE YOUR CAR FOR AT LEAST 30 MINS

-NEXT MORNING CHECK THE LEVEL, ADD COOLANT IF NEEDED

 

Always take care of any leaks and check running temps! BMW cooling system is very important not only for the engine but for transmission as well- tranny cooler is connected to the same main radiator.

Poor condition cooling system will ruin your engine and transmission very quickly. Running with airlock will eventually deteriorate all rubber gaskets including valve seals and stuck piston rings.

Running Rough?? Check engine light? No Problem!!

In this article we are going to cover most common engine error codes and most common issues.

So don’t be freaked out with CEL and don’t rush into BMW dealer- its not that complicated to diagnose it yourself.

First you need BMW software (INPA, RHEINGOLD, DIS, GT) or even simple OBD reader can be of great help. Any check engine light can be diagnosed with OBD reader, though you cannot go in details, but in most cases is enough.

So you got error codes, now its time to decode them online so you know what those error codes mean.

Good idea to check fuel trims and O2 sensor adaptations, it will tell you if you have any vacuum leaks, which will make your engine run very inefficiently, shaking etc.

NOTE: IF YOU HAVE 0420, 0430 ERROR CODES WHICH TELL YOU THAT CATALYTIC CONVERTERS ARE NO GOOD ANYMORE, IT MEANS YOUR ENGINE IS BURNING OIL KILLING CATS, SO NEW CATS WILL  NOT LAST IF YOU DON’T FIX INITIAL PROBLEM WITH VALVE SEALS!! CATALYTIC CONVERTERS CAN EASILY LAST 300-400K, AND THEIR FAILURE INDICATES INTERNAL ENGINE PROBLEMS…

 

MOST COMMON AIR LEAKS:

-CCV or crankcase breathers. Cracked old membrane will create air leak, so DME will increase fuel trim, making it running rich

-VACUUM PUMP SEALS AND OIL SWITCH will create vacuum leak as well. They always leak after 5 years or so. Solution is simple- RTV or new seals from BMP DESIGN company, since bmw only sells small oring and they want you to buy 300$ vacuum pump instead.

-old oil cap will also create vacuum leak

-leaking valve cover gaskets will also create air leaks and more importantly leaking spark plug pipes will create misfires due to fouling ignition coils. If you remove a coil and its covered with oil, it means its leaking and VCG (valve cover gaskets) need to be replaced asap.

-old rubber intake boot is very common issue on N62b48 engine or BMW 750i, BMW 750LI

-intake manifold gaskets and injector o-rings also don’t last forever

 

But be aware that some error codes not necessarily mean you need to replace that or these parts. For example running lean or rich does not mean your O2 sensors or catalytic converters are bad. Always check O2 sensor adaptations, and if they adjust mixture and not stuck, it means youve got something else causing rich or lean mixture and O2 sensors have to adapt the mixture.

 

Sometimes bad Valvetronic or VVTI sensors don’t throw error codes but make engine run rough., you can always disconnect VVTI sensor and your engine will run using conventional throttle body approach, and if it runs smooth without VVTI, it means VVTI sensor is not working well or not adapted.

ABS, DSC, BRAKE LIGHT CHRISTMAS TREE?? NO PROBLEM!!

 

So you got very nice Christmas tree on your dashboard?? Well dont worry it happens sooner or later to any BMW. So one of a sudden all lights are on and IDRIVE is going crazy?

Don’t worry it can be fixed I under 200$!!

MOST COMMON CULPRIT IS YOUR ABS, DSC UNIT !!! IT DOES GO BAD VERY OFTEN DUE TO AGE AND HEAT UNDER THE HOOD!! There could be other things (abs sensors, harness issues, etc) causing those lights, but if all lights are on especially angle sensor light is on, it means module is dying, MOST COMMON DSC/ABS MODULE FAILURE SYMPTOM-NO ERRORS WHEN COLD AND AFTER ITS WARMED UP EVERYTHING IS BAD.

There are 2 options about it:

-Repair DSC module with warranty (best cheapest option). Don’t buy used one- it might not last and can also be bad and worst part you have to code it, which is not very simple procedure. Always try to fix it or get new one, WHICH IS SELF CODING AND WILL CODE ITSELF AFTER YOU PUT IT IN.

-Buy new module for 600$, self coding- will code itself after you installed it. Great option, but I think rebuilt one is better since its going to be stronger than OEM.

 

Replacing is easy: remove the unit, send it for repair or replace it with new one. Located on passenger side, black unit. You need to remove coolant tank to get access to all bolts holding it.

 

So it wasn’t very bad, isn’t it? Enjoy fully working dsc system, it will also affect transmission shifting, because its reading lots of signals form DSC unit. Bmw dealer will charge you more than 1200$ for it.
