Touareg :: 2004 V6 - Fault Code U0121 / Lost Communication With ABS Module
Jun 4, 2008
I have an 04 V6, yesterday it was perfectly fine...last night we had torrential down pours, high winds and standing water... not sure if any of that matters, but this morning I went to take the kids to school and my "BRAKE" light, the ABS light, and the exhaust lights were all on. Took it to a local shop and had them check for codes. They said it was U0121... lost communication with ABS module. What should I do? I drove it a couple of miles back to the house and again earlier this evening to see if anything felt different, but all seems the same.

I recently received an airbag fault light so I figured that I would scan the module for error codes. This is what I came up with:
Control Module Part Number: 3D0 909 601 C
Component and/or Version: 05 Airbag 8.4E++H01 0352
Software Coding: 0012341
Work Shop Code: WSC 31414
Additional Info: 7L0959339B BF-Gewichtsens. 005 0006
Additional Info: Geraet 00000
2 Faults Found:
01217 - Side Airbag Igniter: Driver Side (N199)
001 - Upper Limit Exceeded - Intermittent
01316 - ABS Control Module
004 - No Signal/Communication - Intermittent
Has scanned the car while had the airbag fault present and if so, is this the usual harness that needs to be changed?

When I try to connect to module 9 via vag-com to add DRL and TPS to my menu I keep getting the error on my laptop. How can I fix this? Also how do I remove the acceptance screen from an '06 DVD NAV?

This is a 2008 Prius with no check engine light or other operational issues. The car runs fine. When doing a health check with a Techstream scanner (new toy), it shows the code U0073 along with U0123, 124, 126, and 293. Need to further diagnose what may be wrong?

The code the R threw was p0606 which is the Powertrain/ Engine control module? Where these components are in my R? Or how I can go about trouble shooting this problem?

What would make the OBD II not read the code that is set on my truck. It says "Communication Error..." Fuse 41 grants power to the Diagnostics port and the cigarette lighter. The cigarette lighter is working. Any other reasons I can look at?

So my 6.7 left me hanging the other day, went to start nothing. Towed it into town started. Went to start it couple days later nothing. Jump the plug by right battery starter turns. When key is turned to run no glow plug light, no fuel pump prime. Tested ignition switch good. Tried 2 new Batteries nothing. got power on fuse 52, continuity from fuse 52 to pcm connector. Fuse 49 and 50 also have power. Took all 3 connectors at pcm out and blowed air through and sprayed W.D nothing. Even tried with connector on transmission. Scan tool will not communicate with pcm.
Codes after cleared:
instrument cluster:
uo100 lost communication to pcm
u300a-64 ignition switch...
transmission:
u0294 lost communication with pcm
Body control module:
u0100-87 lost communication with pcm
B10f1-14 key in switch short to ground or open

With all DTCs cleared, this fault code would occur without even shifting out of Park. VW replaced both ECMs, fuel filters and O2 sensors and the car ran fine for the next 1400 miles.
At which point, I decided to get a tune - the car drives great (power gain = ~60hp/90tq. However, I am back to the P0173 fault code exhibiting the same behavior. There are no driveability issues, in fact the new tune seems to be a little smoother than the stock tune. Why this is happening again.

2008 Prius recently lost acceleration (would only creep along) and soon stopped. Warning lights - red triangle with !, red split car on mid, check engine - came on. About 10 minutes later the car started and allowed my daughter to creep the last 1/4 mile home. DTC's - P0A3F and P2196. Was recently gassed up, so checked gas cap, thinking it may have set the oxygen sensor code. It was loose, tightened it. Pulled the EFI fuse for a couple minutes to reset the codes (not sure it did). Put the smart key back in and warning lights came on again. May have to take to dealer, but would like to have some notion as to what's causing this. Possibly related -- a couple weeks ago the 12V battery got drained overnight. Pulled it and recharged and everything seemed to be running fine.

Yesterday our t-reg locked up on us, the Brake fault warning saying "Stop brake fault" came up, but the car was at a full stop. It was in park and I could not get it out of park, this has occured several times before but the dealer never found a problem, with a few repetitions of starting the engine and turning it off seemed to clear the fault. Not this time, just locked up, Also the air suspension fault warning came on with two clicking sounds, one from under the dash just above the accelerator and the other coming from the ignition switch. The dealer now says wait a week and he will look at it saying he would have to quote "tear into it" to look for a potential wiring harness problem. Our 2004 T-reg has been in the shop probably no less than 50 times in the last 4 years....

2007 Prius with 112k. It's getting the red triangle and check engine with code P3012. My understanding is P3012 points to 'Battery Block 2 Becomes Weak'. Battery block 2 is the 3rd and 4th modules counting from the end where the ECU is. These two modules test out the same as the other 26 modules in this pack, ranging from 7.40 to 7.46.
I got them this low by running A/C on high with car in neutral, hoping the bad module would show up. (Neutral prevents engine from charging HV battery.)

So I swapped an R motor into my 20th anniversary GTi. It idles fine as soon as I rev it and the idle comes back down it starts breaking up and I get a code for exhaust flap no communication. Of course, there is no communication since I don't have one. Is there a way to code this out or to trick the ECU to make it think its there? As soon as i clear the code the car runs fine, even if I just turn the car off and back on, it runs fine.

What could cause code P0607 - Control Module Performance?
Truck seems to be driving fine (except it just recently developed what I think is either the cam phaser tick or an exhaust manifold leak on the passenger side).
I haven't tried clearing the code to see if it comes back. This is on a 2006 F150 FX4 with the 5.4L...

While I was driving my car suddenly was losing power.I tried to hit the "gas" pedal harder and it didn't react.It stayed on the same gear and after 2-3 seconds it was ok. After 10 minutes it happened again but this time I couldn't do anything. I thought it was the transmission problem so I went into manual mode to shift it down. It didn't work at all - I was shifting down but didn't have power so I had to stop. I stopped put in P turn engine on and everything came back to normal.It's worth mentioning that one time time I had to pull over and I didn't turn the car off. After couple minutes the car started to vibrate and died. I turned on and everything was ok. Fuel filter or is it something else?

I have been posting about P3125 fault which is inhibiting ICE from starting. During this time I have been charging and also testing the traction battery so that I could continue to investigate the P3125 problem.

My van is spouting SRS fault codes 1-3 and 5-1. I had my shop run a diagnosis and it appears the module has failed. I'm having trouble tracking down a replacement. The Module on my van is Ford# F5AF-14BO56-AA. I see modules with -AD or -BD, but none that match this number perfectly. I also see lots of modules for related Ford vehicles from the same era. Looking for a ford parts number reference sheet that will indicate on what vehicles this module was used or if there is any chance that related modules are compatible?

Since we know that most VW service sucks, I'm taking my 04 V8, Nav/Air Susp 35k miles in tomorrow because the whistling/rubbing noise was bad enough on the ride home from work last night that it started freaking me out.
I want to tell the service department to at LEAST check the following:
Whistling: Gets worse with speed and when the car gets warmed up. Sounds more like rubbing when you get going. Check the drive shaft bearing.
Running Gear Fault: Check air suspension piston rings ( I need to look this up again) Something to do with the air bag or air pump seal.
Hesitation: There should be a TSB for this that can be fixed with a computer adjustment.

Have an 04 Touareg V8 with a tire pressure monitoring system fault. Dealer says that one of the sensors is bad - $400 to fix. Have heard that the TPMS in the 04 was bad, removed in 05.

I have an 04 - V6 with about 55k miles. Tire Pressure Monitor System Fault is the message. The tire pressures are fine. Message appears after 15 minutes or so of driving. After another 5 minutes or so of driving, the fault message goes away - whey you click to vehicle status it says "OK". I took it to my local VW dealer, they said they fixed it, but on the way home from the dealer, it popped up again. They are perplexed. This is not the "Faulty wheel on board" message, it is totally different....
