Hi,
Im a first time Audi owner - having recently purchased an '05 Audi A6 (4F) with 53,000 miles on it. The car came with a "parking brake malfunction" error although the rakes seem to apply and release fine. The dealer told me that the control module needs to be replaced at a cost of over $800.

My questions are:
1. What is the part number for this module?
2. Where is it located and what is the procedure to replace it?
3. Will I need to do any coding to replace it or is it "plug & play"?

Im hoping to post developments with pictures as i go along so for others to use in the future. Thanks!

Welcome! Its very easy to replace. Its in the trunk on the right, under the tools. No coding required. IIRC it costs less than $300 from an online audi dealer.
Hope it helps

There is a TSB in the brake section of the TSB library linked in my signature.

@jeffry:
1. Yes - there is just a big yellow crossed out "P".
2. There is no ABS or EPS lights on.
3. I hear a loud beep (repeated 3 or 4 times). This does not happen everytime - only once every 10 - 15 times i turn the car on. No additional lights or errors pop up along with the beeps.
4. I unfortunately do not have a VAG-COM or any computer codes.

@kevingary:
1. Thanks! I looked at the TSB and also showed it to the dealership. They hadn't checked it out initially - after i insisted, they came back to me and said that it didn't solve the problem.
2. They suggested that I need to replace the control module.

@ freshfrompacificrim:
1. Thanks!
2. Do you know the part #? I think its this: http://goo.gl/iVIC1 but i'm not sure.

I believe thats the part.
When this happened to me, diagnosing through vagcom, i discovered the wire was frayed right at the right parking brake connector on the caliper, so I just pulled back the rubber sleeve, and soldered it. Problem solved.

Gladly

can anyone let me know if the audi's have a relay for the electric parking brake motor and where its located or does it only have a fuse
