What is the 4.2 TDI V8?
It is the eight-cylinder diesel of the Cayenne S Diesel, with enormous torque. It is covered in our catalogue with 57 specific files.
Is a remap noticeable on such a powerful vehicle?
Yes, particularly in mid-range delivery. Even from very high factory figures, forced induction leaves margin to work with.
Is the work reversible?
Yes. We always keep the original ECU file, which matters particularly on a vehicle of this value.
