About remapping
The Audi TT accounts for 763 files in our catalogue, and here petrol rules entirely: the 2.0 TFSI leads with 206 files, alongside the earlier 1.8T and the 1.8 TFSI. The 2.0 TDI covers the diesel side in smaller numbers. It is a compact sports coupe with a strong tuning tradition.
Stage 1 makes up 601 files, with 123 Stage 2 and even 7 Stage 3 — a spread that shows how far these cars are taken. The ECUs are ME7.5, MED9.1, MED9.1.5, MED17.5, MED17.1 and SIMOS18, covering several generations of the model.
