hi there. i'm new to the forum and i could do with some help with my car. the car is a 1993 audi 80 1.9 tdi (66kw). recently the check engine light has been appearing on every journey. when the engine is turned off and back on, the light disappears until some point through the journey. there is no pattern to when it turns on. it could be when going fast, slow, straight ahead, when the engine is cold or hot. driveability does not seem to suffer at all. anyone offer some help please??
