I want to note that VCDS cannot be error free unless you put original AUDI LCD back and our device removed. I just want to clarify otherwise i will be bombarded with emails how to make vcds look clean.

Also, Audi technicians does not use VCDS, but ODIS.

Finally, I have to tell that your case is an isolated case where majority of people do not have parking brake issue, and only two out of 300+ were reported.

Please do not generalize as if pbc issue is common.

I would say parking guideline malfunction is common, but not to your case.

I have still doubt that your parking brake controller may be defective.

Once I had someone complains alternator noise since installation of our device, i warned him possible pcv valve issue, but he ignored and then his timing jumped with pcv valve failure along with the tensioner failure.
