#1361 of 1404 ABS indicator light by eric127

Nov 21, 2011 (10:09 am)

I have a 2004 A6 2.7 S-line with 58k miles. just recently the ABS light will randomly come on, later go off.. the check engine light also has appeared, then gone off.. Audi and another mechanic both told me the ABS light was the left rear wheel speed sensor, which i had someone other than Audi replace. That didnt fix the ABS light from returning. He said it could be the wiring, or maybe the brake control module, but wont know until he replaces these expensive checks..
I primarily use this car to take me to the train station and thought about ignoring it.. but it is a nice car and ABS is a safe feature to ignore.
does anyone have an idea if this is the best way to fix this problem..

when i turn key in ignition, the cars selected gear panel shows that all gears are selected, after turning key back and forth for up to 25 minutes, a light reading "esp" on the speedo side will come on and car will then correctly display that it is in "park" and start properly and run completely normal, can anyone help with a diagnosios to this problem ?

Greetings ptjaudi! Sorry this took so long.
Your ignition switch and the control units for Vehicle start authorization are most likely the area where the problem is. I say most likely because you will need to have a "Authorized Service Center" or reputable Repair shop familiar with older Audi A6 Sedan 4B2/C5 electronics run a diagnostic test for error codes to pin point the problem. Unless you have a "VagCom" diagnostic tester and considerable Electronics/software knowledge this is not a job for DIY (Do it yourself repair). In my opinion, you will need Audi to solve this problem, either through there Web Page, Erwin.com or a dealer. Electronics are always a difficult task and all but impossible to diagnose over the internet, in particular with older vehicles.
Over the last ten plus or so years, Audi has moved to HiTec Components and electronics. The up-side is more efficient vehicles when they operate correctly, but when a problem arises, it's $$$$'s that solve the problem. I hope this will save you some time.
Best Regards

#1366 of 1404 Problem with engine stalling 2008 A6 3.2L V6 by clylesjr

I've just gone over 50k miles (put on 120+ miles a day). Beginning last week, car stalled on a Tuesday and I had it towed. I could start the car but it continuously cut-off. Next day, car ran fine until Thursday. Car stalled again with same problems existing. Checked oil and it appeared to be extremely low. Car towed to dealership and they had it for 2 days and found nothing wrong other than the need for an oil change.
 
I have had the car back for 2 days and it just stalled out again around 7pm. Left the car, came back to it at 9pm and the car is running like nothing happened.
 
Any idea what I should be telling the tech to look for?

Hi Clylesir,
To start with if they had your car for two days and did not find anything wrong you need to
seriously find a better Audi Service Center, even if you purchased the car there.
Tell me, did they "The Service Dept." of your Audi dealer do a Diagnostic read out and not give you a copy and charge you for that Diagnostic read out on your "Oil Change Reciept"????????? Shame on Them my friend.
If not go back and get one, any error codes in particular from the Engine electronics, engine Temperature and fuel systems.
Then find out if there are Technical Service bullitens,(TSB's) regarding your specific problem.
Another question:
Does the car always start and run until the engine gets warm then stall?
I don't know if your current model is the same but in the 99 A6 The Engine temperature sensor is a dual sensor and measures Engine Water Temperature and Fuel pressure.
DOES IT STOP WHILE DRIVING??????
DO YOU HAVE ANY WARNING LIGHTS on the Instrument Cluster before the problem happens???
Get back to me with that Info.
Thanks

Yep, that's a pretty sad Audi dealer. If you are in the San Francisco Bay Area, I can refer you to Audi people who actually know what they are doing.

Regarding diagnostic --Tech message stated "scanned no codes and could not duplicate concern. The car sat through wknd...I started up and drove the car again and could not duplicate concern." I didn't see a charge other than oil change receipt and did not receive a copy of the diagnostic read out.
 
The stalls have happened at various times (15 minutes into drive after sitting during work day; stalled after sitting for a 10 minute period between stops; stalled after 1 1/2 commute when backing out of driveway)
 
2 out of 3 stalls occurred while I was driving and never at a speed level above 15 - 20mph.
 
There have been no warning lights prior to the 3 incidents.
 
I was able to drive it to the dealer today (20 minutes approx) without any problems. Left it and waiting to see what's next.
 
Thanks JK...
