My 2005 Audi A4 2.0T Quattro has developed a problem of some sort and now I have the EPC and Engine icon lights on. During the cold spell a few weeks ago my engine management light (engine icon) popped on for about 15-minutes on a journey, however it reset itself and I just put it down to the cold weather. However the other day the EPC light came on the dash followed by the engine management light a few minutes later. My local mechanic mate has just plugged his reader in and the following details have come up;
Internal control module. Check some error.

The car drives fine, although it does stutter a little when cold if you apply too much right foot. Although I'm not sure if this is normal as I've only owned the car a few months! The car does have an AMD map which was put on the car when it was 1-year old by the Audi main Dealer.
