hi my name is kevin and i recently bought a 2000 audi S4. it is my first audi and i like it. the question i have is that my epc light always comes on. some days when the car starts it is on, others it comes on when i drive for more than .5 hours. the engine is not particularly hot or anything. i recently had the opportunity to smoke a wrx but my my damn turbos were down due to the epc. does anybody have any advice to make my engine more consistant.    thank you     sdmarv at att.net
