Audi a4 b8. 2.0 tdi 170 quattro Recently had my abs, traction control and hand brake warning come up on the dash while driving along. Sometimes after switching off the car and back on it will stay off. Sometimes after driving with the lights off and parking up overnight when I start it up the next morning the lights come back on. Also noticed when lights are on the engine won't switch off with the first press of the key. Have to push it a few times. Had it scanned with vcds Pictures should be below!
