Audi A3 e-tron ECU remapping
7 files available

About remapping
The Audi A3 e-tron accounts for 7 files in our catalogue, entirely the 1.4 TSI and TFSI turbocharged petrol in its plug-in hybrid application. It is the electrified version of the compact.
Stage 2 leads with 4 files against 2 Stage 1. The ECUs are MED17.1.21 and MED17.1.2. On a hybrid we work with particular care, because the combustion engine operates alongside the electric system.

Can a plug-in hybrid be remapped?
Yes, working on the combustion engine's ECU. We do it with particular care so the change does not disturb how the electric system interacts with it.
Does it affect electric range?
No. The electric range depends on the battery and the electrical system, which the work does not touch.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
