About remapping
The Mercedes-Benz E-Class accounts for 5,143 files in our catalogue, led by the 2.2 CDI four-cylinder in its many designations, alongside the 3.0 CDI V6 and the BlueEfficiency variants. It is an executive saloon where refinement matters as much as outright performance, and the map should reflect that.
Stage 1 makes up 4,400 files, with 816 EGR off, 528 speed limiter removals and 515 DPF off. The ECUs are predominantly Delphi CRD2 and CRD3 on the CDI engines, alongside Bosch EDC16C31, EDC16CP31 and EDC17CP10, plus the more recent MD1CP001. Every job starts from the original file.

What should I expect from an E-Class remap?
The aim is fuller mid-range pull without losing the refinement the model is known for. In an executive saloon, flexibility matters more than headline figures.
Do you work with Delphi CRD ECUs?
Yes, the CRD2 and CRD3 are the most common units on Mercedes CDI engines and we cover them comprehensively.
Can I run with the DPF disabled?
Not on public roads: regulations require emissions systems to remain operational. These files exist for specific applications; ask us about your case before ordering anything.
