Hi guys, i have 2002 a6 2.7t quattro with about 90000 miles. Lately the car been acting funny... and the MIL light came on. I forgot what the code was exactly but it said something about brake booster malfunction. I was wondering if that could cause my brakes to lock up. The car drives okay for a few mins and then it feels like that the brakes lock up. If i turn off the car and start it the same process repeats... I was wondering if the car was doing this on purpose to prevent an accident or there is something else wrong with my car. Could this be related to the brake booster problem? Any advice and comments are welcomed
