2005 Audi A6 Electronic stability control Problems

“Driving 55 MPH on the express way and the engine shut off completely. The car stalled until it came to a complete stop. The esp light and engine light came on. Restarted the car and problem continue 4 times. After the 4th attempt, I managed to get the car to the side of the road. After waiting several minutes, I restarted the car. The car still feel at times as if its going to stall.”

“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. …”

“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.

“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.

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.”

“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. …”
