 We regularly undertake vehicle diagnostics and specialist electronic repairs including electronic control module replacement to Renault vehicles some of which are detailed below. If you have an Engine control module (ECU), Body control module (BCM or UCH) or Instrument cluster problem with your Renault you will be aware that a secondhand unit cannot be simply fitted as it has to be re-programmed to your vehicle. A diagnostic scanner used by garages & workshops is not capable of programming secondhand ECU's & BCM's, however we are able to 'clone' (Bench program) or in some cases 'Virginise' secondhand units so they will work on your vehicle with no further programming necessary to the keys etc thus making them 'Plug & Play'. We have hundreds of ECU's in stock, if we don't have the unit you need we also offer an ECU cloning service if you can source one for your car, a Europe wide mail order service available - ECU cloning starts at 50+vat. Call us for more information and advice on how we can help you with your requirements.

Renault Megane mk3 mileage repair

 If you have fitted a secondhand ABS pump / ecu to a Renault Megane mk3 (Phase 3) and it had a higher mileage than your car you will have a problem with the mileage changing on your instrument cluster to the higher mileage of the secondhand unit - relax! We are able to correct the mileage on your dashboard display without the need of fitting a CAN blocker! We can simply do the whole job via the OBD socket on your car without the need of removal of your cluster or your ABS pump, we can even do this job while you wait at our workshop in Norwich - please call for price & to book an appointment.

Instrument cluster repair

 Do you have a Renault Scenic 2 with a faulty instrument cluster? Common faults include display LCD failure (usually intermittent) clock resetting & mileage jumping by hundreds, sometimes thousands of miles eventually leading to complete failure of instrument panel. - We can fix this! Simply bring or send us your faulty instrument panel and we will completely refurbish your faulty unit, including resetting the mileage reading to its correct amount and test it on our bench test rig. We even have loan units for you to use whilst we are repairing your faulty unit. Price for full refurbishment is 79+vat - Europe wide mail order service available.

Airbag Crash data removal

 We can remove crash data from most airbag control units fitted to Renault 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. Crash data removal starts from 40+vat - please call for more info

Mail order service available
