Frequently asked questions

An ECU file is a binary read-out of an engine or transmission control unit's flash memory (and often its EEPROM). Our catalogue contains original factory reads plus solutions such as immo off, virgin, DPF/EGR/AdBlue off and Stage 1 tuning, each identified by hardware and software number.

Compare the hardware number (e.g. 0281017946), the software number (e.g. 1037541778) and, where shown, the manufacturer part number with the identification your tool reports. All three are listed on every product page. If anything differs, request the file instead — never write a mismatched file.
