About remapping

The Audi A3 accounts for 2,684 files in our catalogue, with a genuinely balanced spread between the diesel TDI range — 2.0 TDI, 1.6 TDI and the older PD units — and the petrol turbos: 1.4 TFSI, 1.8 TFSI and 2.0 TFSI. It is a premium compact used across a very wide range of driving styles.

Stage 1 makes up 2,287 files, with 314 EGR off and 244 Stage 2. The ECU spread covers EDC17C64, EDC17CP14, EDC17C46 and PCR2.1 on the diesels, MED17.5 on the petrol turbos and EDC16U34 on earlier units. Every file starts from the original read of the ECU.

Frequently asked questions

Which A3 engine offers the most headroom?

The 2.0 TFSI petrol turbo delivers the largest gains in outright figures, while the 2.0 TDI is exceptional for usable everyday torque.

Do you cover the 1.4 TFSI?

Yes, it is well represented in our catalogue. Being turbocharged, it offers a worthwhile margin despite its modest displacement.

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.

Data comes from our project history. Exact availability is confirmed when you request the file.
