Hi Folks, I've just yesterday picked up a new Dolphin Grey A3 TDI 170 S-Line with the S-Tronic box, I'm just going through the tedium that is running in... Does anyone know definitavely if the engine in the 170 is a PD or a Common Rail unit? I see a lot of conflicting information about what it is, although the Audi site says it's a CR. Not that it really matters too much, I'm just the curious type! Phil.
