Hi. I have just joined the forum today and hope for some good advice. My audi was fine until a few days ago when the parking malfunction warning light came on. After switching off and leaving a few minutes the warning light tends to go away then maybe reappear 2/3 days later. Was going to sell car this week but would not if car has a problem. Thee does not seem to be a problem with the parking brake. Any ideas? I have read that this is a common problem on other forums. My car is an a6 with 71k and is the new model on a 54 plate.
