I am just looking at a 2010 Audi A4 2.0 TDI S line Start Stop and am not sure if it is a 143 or not. It is advertised as a 143 but in the logbook all it states is Audi A4 2.0 TDI S line (or something like that). It does not show the power value anywhere on the logbook. Does your logbook show this (if you have the S line 143)? Looking at the Parkers Car Specs there are 3 engines it can be: 2.0 TDI (136bhp) S line (Start Stop) 4d 2.0 TDI S Line (Start Stop) 4d 2.0 TDI (143bhp) S Line (Start Stop) 4d Any help would be appreciated.
