About this file

Typical uses: restoring a control unit to its factory software after a failed flash or a corrupt memory, a clean base before any change, comparing a read of your own with the original. The checksum is the one of the read; your programmer or the CARTESIAN app corrects it after a change.

In CARTESIAN this original file is the base for the solutions it supports, such as DPF off, EGR off, lambda off and DTC off, each saved with a correct checksum, and for returning a modified unit to stock.

Before you write Compare the numbers on your control unit with this file, hardware number O_C66S86 and software number 1037387658. A file written to a unit with other numbers can damage it. Not sure? Give your own read to the search above: it is compared by content.
