Has anyone done this,car is an A3 TDI quattro, 2005. Is it easy or difficult, what's involved, also part numbers for the relevant pedals would be helpful. I had a look on Soke Audi and they seem to list 2 accelerator pedals, one for manual, one auto but nothing different from Petrol to Diesel, does this sound right, they do also say to phone to check yo are getting the right parts. Accelerator is my main worry as it has to be right, the rest are just replacement covers I am sure.
