Firmware with the number 0CW
0CW is the Gen 2 DQ200. The gearbox can look like an older 0AM from the outside, but the software is different. Search 0CW in the catalog, and choose Gen 2 in the Immo Off form.
The version next to the number
The label has a version after 0CW. Add it to the search after a space when you know it. An exact match opens one page instead of a long list.
Writing
Do not write an 0CW file into a unit whose label says 0AM. The file costs 20 €.
Gen 2 Immo Off
Moving the unit needs your flash and EEPROM, not someone else's catalog file. The service costs 30 €.
Where to do this
A firmware file from the catalog or by VIN costs 20 €. Immo Off together with the VIN change costs 30 €. The download button appears after payment and a copy is sent by email. If that version is not in the database, there is no button. Before writing, match the software number and version to the unit label.
