My 2007 Audi A6 4.2 Quatro is giving a message to "put car in park' when it is actually in park. When this message appears the doors do not lock and the key will not come out of the ignition. This is the second time this has occurred. Had it repaired by replacing the brake switch. Two weeks later the problem re-occurs.

Please help

 

Have you had your transmission recently serviced prior to the message?
