How it works

Validated and checksum-corrected

Detect the ECU

The diesel ECU family is identified automatically from the uploaded file.

Apply DPF off

The validated DPF off module is applied; pair it with EGR/AdBlue off and DTC removal as needed.

Correct checksums

Checksums are recalculated automatically so the file is accepted by the ECU.
