About remapping
The Mercedes-Benz C-Class accounts for 4,779 files in our catalogue, with the 2.2 CDI and 2.1 CDI four-cylinder diesels leading the way, alongside the 2.0T petrol in the more performance-oriented versions. It is a compact executive saloon used daily by a very wide range of owners.
Stage 1 makes up 3,999 files, followed by 569 speed limiter removals and 406 Stage 2. The ECU mix is broad: Delphi CRD2 and CRD3 and DCM3.2 on the diesels, Bosch EDC16C31 on earlier units and MED17.7.2 and ME9.7 on the petrol versions. All work begins from the original ECU read.

Which C-Class engine is best covered?
The 2.2 CDI and 2.1 CDI four-cylinder diesels account for the bulk of the catalogue, though the 2.0T petrol is also well represented.
How much will I notice on a 220 CDI?
Mainly mid-range torque, which is where the car spends most of its time. It makes overtaking easier and reduces the need to change down on inclines.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration whenever needed.
