Can anyone tell me if the 2.8 V6 was ever installed in a car WITHOUT OBD ? Car is a UK 92 90 quattro and Audi dealership claim that it's 'too early to have OBD on it'. (I have to say that the dealership haven't seen the car yet.) P.S. The fuse box has the K and L connecters and these are detailed on the fuse box lid too. Simon.
