Vauxhall ECU types. Units suitable for diagnostic de-coding
De-coding and code reading enables us to reprogramme some ECUs, or change the codes that prevent electronic access to enable the unit to be programmed in the event of a fault. Below are the most common Vauxhall ECU units that we are able to de-code and programme. The list is constantly changing, as new and updated software is released. Please contact us even if your unit is not listed here.
Please note that for many models, parts of the unit's coding are a 'one time only' system. This means that the ECU will only be able to be correctly programmed for the vehicle it was originally fitted to. If you have a problem with a vehicle ECU, please contact us to check before considering purchasing a used unit, as it might be impossible to re-programme it correctly for your vehicle.
