ECU Programming

 If you have an ECU problem with a BMW vehicle you will be aware that the Engine ECU (ECM) and Immobiliser (EWS / CAS) is programmed to each other (Locked). A diagnostic scanner used by garages & workshops is not capable of re-programming secondhand units, however we are able to bench program (Data swap or 'clone') secondhand units enabling them to be re-used needing no further programming necessary. We stock various BMW & Mini ECU's, if we don't have your unit available we offer a cloning service if you can supply a donor unit - all you have to do is simply send us your original & donor units, prices to clone an ECU or Immobiliser starts at 50+vat. We also offer a Europe wide mail order service. Call us for more information and advice on how we can help you with your requirements.

Airbag Crash data removal

We can remove crash data from most airbag control units fitted to BMW vehicles. Crash data needs to be removed from SRS control units after a car has had collision and a safety feature has been activated such as seat belt pre-tensioners, airbags, fuel cut-off systems etc. This usually appears as the airbag warning light being illuminated and fails to extinguish when garages try to clear fault codes with a standard diagnostic scanner. Simply remove your airbag control unit, bring it to us for stripping and re-programming and usually it will be ready for collection within 24 hours, Prices start from 40+vat
