Default Parking Brake Malfunction

I have a 2005 A6 that I purchased in January 2005. It has 42,000 miles on it and the warranty expired last week.The Parking Brake Malfunction light came on yesterday and I took it to my local dealer. He tells me I have a faulty computer which has to be replaced - total cost $900. I have never even used the parking brake and the computer goes out. I am having it replaced tomorrow at my expense, but this really hacks me off. Has anyone else run into a failure like this?

yea, I bought a 2005 at auction in September. I drove it home and parked it on a slope, set the brake. When I got in next to move it, the parking brake malfunction light lit up, and the brake was stuck. I could not move the car! However, the car sat overnight and was fine in the morning.

I looked in the trunk (behind the tire changing tools), and saw that the parking brake controller had been fixed (which I think is the computer you refer to). The old one was in the trunk, and the new one was just sitting there, so I suspect that Audi tossed it in, deleted the fault code and sent it to auction. I also reset the code, and haven't had another issue since (of course I haven't used the brake since either).

There is a TSB on this issue also, if you search for it,...

I've got the same issue. How do I get the TSB? I'd pm Kevin if I could figure out how to do it.

Just had MMI module replaced in my 05 and I think it may be related.

Hi all - I have a 2004 3.0 A6 and have had problems with the parking brake since I bought it. Everything else about the car is great but now the parking brake warning light comes on along with a red exclamation mark and the car will not move.

Could someone please point me to where I can get the TSB that deals with this issue? I have already had the dealer replace the parking brake control module ($1000AUD) and that temporarily stopped the problem. And Audi also cleared the error codes but the car is now stuck with one of the parking brake motors locked on.

Many thanks

Ebolaboy.

I gave the TSB to my SA and they tried to upgrade the software for the EPB, but they kept getting an error. I think he said that they tried two times - finally gave up and have now ordered a new control module for this. Got this in at the nick of warranty period expiring. Car now has 498xx miles. I sure would have hated to spend $900 had this thing happened after warranty was over.

update on my car (2nd post in this thread). My father borrowed it and set the brake - it locked up again (I haven't used the parking brake since I bought it about 1 year ago). I brought it to the shop to repair - and found out it is the switch itself that is bad! $65 part, so not too bad (they had to order it and so I don't know the labor cost yet).

Default A6 Park Brake Update

Guys - bad news on the park brake problem. I have had this car back to Audi 3 times to finally get it resolved.

First time they replaced the park brake control module and told me the problem was fixed.

Within 24 hours the park brake had again locked the car up and immobilised it. The car could not be moved at all as the right rear park brake motor had failed while engaged. An Audi mechanic told me over the phone that I needed to unplug the cable connecting the motor to the electrical system, undo the two screws that held the motor in place and then turn the torque screw until the brake was no longer engaged and the car could be driven.

This sounded simple over the phone but harder in practice and I was not able to complete the work. Despite this, the work must have disengaged the brake because the car could at least be driven.

After Audi replaced the right rear park brake motor and told me it was fixed, the problem came back after 24 hours and the car was again immobilised. Turning the ignition on and off again resolved the problem temporarily and enabled me to drive the car back to Audi the next day.

On the third attempt to fix the problem, the Audi technician reported that the contacts on the plug connected to the park motor were dirty and wwere causing the problem. That was yesterday. I'll wait to see if it really is fixed.

The upshot is that I don't think that the TSB is going to help you!

Cheers

Where can we find the TSB's on the net for the C6..obviously Kevin has a source, maybe we can set up a place just for TSB files?
