Is this the same as the main A3 entry?
It is the same model recorded under a different designation in our history. Each group covers different units, so it is worth checking both entries.
What does the 2.0 TDI gain?
Mainly mid-range torque, which is immediately noticeable in everyday driving. It is one of the most rewarding engines we work on.
Do you cover the older 1.9 TDI?
Yes, it is present in this group alongside the more modern common-rail units.
