I've just bought an April 09 A4 Cabriolet 2.0 TDI S-Line and was hoping you could help me out? I know the A4 saloon uses the common rail engine but does the cabriolet? I'm not sure if mine is the PD or CR engine...reason being is i'm looking at Celtic Tuning for a wee tweak - the PD engine allows for the eMotion and the CR doesn't....any help is gratefully accepted - thanks
