Gearbox TCU firmware
Here the TCU is the gearbox control unit, the electronics of the mechatronic, not the engine unit. TCU firmware is that unit's file. Match it by the software number on the label or by the car VIN.
Which TCUs are in the catalog
The filters are DQ200, DQ250, DQ381, DQ500, DQ400, VL381, VL380, DL501 and DL382. The word TCU without a number does not select a file.
Recovery and a transfer
Restoring the software is the catalog or the VIN, 20 €. Moving a unit to another car with your own dump is Immo Off, and only for DQ200, DQ250, DQ381 and DQ500.
Not the engine
Engine ECU firmware, chip tuning and the key immobilizer are not done on this site.
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.
