As u all probably know i now have a pre facelift B5 S4 Avant. Im having a prolem with it at the moment. The EPC light keeps coming on, on the dash. On top of this the idle seems to fluctuate from 800-1050rpm and when driving it will slightly jolt. I thought the throttle position sensor was going but i had vag com on it yesterday and no codes were recorded on the ecu. Im sure all the symptoms are related as they only starting happening once this light starting coming on.
The light itself only comes on every now and then. Yesterday it came on for my whole 40 minute journey then when i got home turned the car off then turned it on agin the light went off???? Any ideas would be much appreciated
