Hello dear audiforums members.

I have following issue on my Audi A4 3.0 Quattro 2002yr. TipTronic
During driving the brake system blocks the car, it is hard to accelerate, fuel wastage goes up and finally you can not move. Brake pedal is like a rock. When you try to accelerate ABS and ESP lights appear. When you turn off engine and start again some noise appears in the brake and gas pedal area. When I have checked the disks they were hot, mostly front ones.
After a 30 min approx. car can drive but not for a long time. I have 2 questions: 1. what can be the reason of the problem? and 2. could this reason be brake light switch?
Thank you in advance for assistance and looking forward to handle with this issue soonest possible.

 

Get the car scanned for codes (using Vagcom, so you can scan braking and chassis codes, not just engine codes). I'm thinking either an ABS or ESP malfunction or possibly seized calipers, based on your description.
