Today drove my A4 to a nearby shop to run an errand. On my way back, the car wouldn't start. The engine finally started after 4 attempts, but the the Electronic Power Control (EPC) light stayed on. I drove back home (only a 2-3 miles) with the light on. I noticed that the engine was idling at a higher RPM (1100). After reaching home, I shut off the engine and restarted it twice - both times, it started in one attempt and the EPC light did not stay on. The engine was again idling at its usual RPM (750, I think).
I guess I should still see the dealer? What could be causing this? I would truly appreciate any information. Thanks a lot.
