On 2 separate occasions I had to pay for a parking brake module or motor. The cost was $900 both times. I google this and found more complaints about this same issue.

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.

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.

Electromechanic parking brake broke 6 times in 4 years. A few times the brake won't disengage, having to literally drag the car on a platform to be able to take it to the dealer. Since the first event I've never used the parking brake on purpose (the car is automatic) to avoid another malfunction but it would still break every few months. It's either the motors or wiring or both. It never happened to me while driving but dealer warned me that it could. The reason I'm filing the complaint is that it is not an isolated case. A quick google search "Audi parking brake malfunction" will prove that the problem is widespread and it makes me think that they should have issued a recall but they didn't.
