My dad has an 05 Audi A3 2.0 TDi and the other day the "Emission control system) warning light came on, so off it went to the garage, and they seemed to think that gving the throttle body a clean, because it was clogged up with carbon deposit. After the light went off and a week later it has come back on, has any one had this problem or knows what it could be, Thanks Joe
