Audi A4 ECU remapping
5,500 files available
About remapping
The Audi A4 accounts for 5,500 files in our catalogue, dominated by the 2.0 TDI in all its variants — pump-duse, common rail and DPF versions — alongside the 2.0 TFSI and 1.8 TFSI petrol turbos and the 3.0 TDI V6. It is a saloon that covers an unusually wide span of drivetrains.
Stage 1 makes up 4,604 files, with 750 EGR off and 532 speed limiter removals. The ECU spread reflects that breadth: EDC17CP14, EDC17C46, EDC17CP20 and EDC17C74 on the diesels, EDC16U31 on earlier units and MED17.1 on the petrols. Every file starts from the original read of the ECU.

How does the 2.0 TDI respond to Stage 1?
It is one of the most rewarding engines we work on: the gain in mid-range torque is immediately noticeable in everyday driving, and the unit has proven robust over many years of remapping.
What is the difference between the PD and CR versions?
The pump-duse (PD) units are the earlier design, while common rail (CR) came later with more refined injection control. Both are covered, but they need different files.
Do you cover the 3.0 TDI V6?
Yes, it is present in our catalogue with 155 files, offering strong mid-range gains thanks to its larger displacement.
