Is a remap worthwhile on a small premium car?
Yes, precisely because the car is light and the starting figures modest. The relative gain in torque is very noticeable in everyday driving.
Which engine gains most?
The 1.4 TFSI offers the best balance of headroom and volume in our catalogue, though all the turbo units respond well.
Will it affect my warranty?
A remap is detectable by the manufacturer and can affect warranty cover on engine-related components. We keep the original file so it can be reversed.
