2005 Audi A6: ABS light or ABS activating

Filed Oct 29, 2014 · Brakes, Driver assistance · 93,450 miles · NC

On our 2005 audi a6 we purchased certified pre-owned (cpo) we are the second owners of the vehicle. When we purchased this a6 it had only 30,330 miles. When we got to around 90k+ miles is when we started to have some issues with the cars braking system. We took it to audi which is the only place we have had it serviced and where we purchased the vehicle. They said there was a problem with the brake module causing the blinking brake light and the ABS light to come on along with a loud beeping from time to time. They thought it could also be low on brake fluid and capped it off. The problem went away for a while but then came back along with the check engine light. This time it was said we have a fault ecu module. We had this service done which costs $2,200.usd but this was just to repair the check engine light but not the brake module. We asked if this repair would resolve both issues and the answer was yes. There are thousands of complaints about the bosch brake module which seems to be an ongoing problem with audi. This needs to be recalled and everyone get their money refunded to them for the pain and anguish this has caused. There also needs to be a class action lawsuit against audi!!

Audi 2005 a6 started to have intermittent warning for ABS, stability, hand brake at ~55k miles. Took car to dealer to diagnose it . Dealer called with an estimate of $2800 to replace ABS module. He also provided an estimate of $1100 for another error code for airbag to replace the center rear seat belt. I'm not understanding why these warning codes come so randomly and clear so randomly. Not sure why an audi a6 will need such repairs that clearly point to flaws in design and unreliable parts after only 55k miles. There are tons for online complaints from audi drivers that use the bosch 8.0 ABS module. Audi should either recall this part or offer to pay for the repairs. When I complained to audi USA, basically they asked if I was first owner and if I take it to dealer for maintenance. The answers for both is no. I'm the 2nd driver. Bought the car with only 20k miles and since relocating to houston, I take the car to a local garage for oil change. I'm looking for safecar.gov to rectify the issue with audi. Audi doesn't even sell the ABS module part alone. You will have to buy the brake pump as well.

2005 audi a6 has water damage. Some how over night heavy rain seepage left an inch of water behind driver seat. Car was parked in driveway. All windows and doors where closed. This has caused $10,000.00 electrical damage to modules located under front passenger seat. These modules alert me about esp/ABS and park brake as well as a module that powers the vehicles mmi/navigation and stereo system. None of these function any longer. Insurance company wants to totaled the vehicle,I spent $7000.00 already on repairing the vehicle. Don't know where the water entered my vehicle. Is audi responsible? This appears to be a design flaw.

I was driving my car in my work parking lot when a loud beep occurred and my car issued a warning for "parking break malfunction." two lights, ESC and ABS also lit up when the beep sounded. I immediately stopped driving, engaged the parking brake (which worked) and disengaged it. I am the second owner of the car and after some research found that the brake module and mmi both had been upgraded by the previous owner. I continued to witness these symptoms and am waiting for my dealership to run a diagnostic. I have read enough consumer complaints about this specific problem to know that audi should take a deeper look into it.

My 2005 audi a6 has water damage. Some how over night heavy rain seepage left an inch of water behind driver seat. Car was parked in driveway at a slight incline. All windows and doors where closed. This has caused $2,700 electrical damage to modules located under front passenger seat. These modules alert me about esp/ABS and park brake as well as a module that powers the vehicles mmi/navigation and stereo system. None of these function anylonger. I don't know where the water entered my vehicle. Is audi responsible? This appears to be a design flaw.

My ABS light, parking brake failure, and esp lights all came on at the same time while driving my 2005 audi a6 4.2 s-line model through a sudden snow storm in colorado. My ABS immediately failed and my brakes locked, causing me to lose control of my vehicle, and fortunately I avoided a crash (I was at low speeds). The quattro all wheel drive was also disabled at this time and I was unable to gain traction on the icy road. This could have been a devastating crash resulting in injuries if I had been going the speed limit that night. I immediately took my car in for service on 12/2/09 and was told I needed to have the ABS module replaced at a cost of around $1600. Why was this not a recalled part? According to the service tech at stammler audi in boulder, co it is a very common problem with the 2005 model year because it is the first year to have some new technology involved in the vehicle's driving systems. I am extremely upset that there is nothing I can do but pay out of pocket for a defective part, that audi also agrees with, just to drive safely on the roadways.
