The EPC light on my 2003 Audi a4 has come on several times. The car has shut itself off at stop lights, the car has had some trouble starting up at times, is this common, and do you know what the problem is?
Hello and thank you for using JustAnswer
It is possible you have to do a throttle basic setting procedure, this requires a factory scan tool so you will need to bring it to Audi.
If the throttle basic setting does not work you may need to replace your throttle body.
Take it in for the throttle basic setting and they will let you know.
