At Castle Performance we use the current launch system of vehicle diagnostics for all makes and models. We can diagnose faults and codes for engine management and EPC faults. These are faults relating to emissions and programming in engine and gearbox control units.

In 2012 these warning lights became an MOT testable item and will have to work correctly to pass an MOT test.

Diagnostic procedures are a form of repair that is carried out to your vehicle involving any of the on board vehicle computer systems. This can range from Engine Management, Anti-Lock brakes (ABS), Electronic Park Brake (EPB), Traction Control and DSC faults, Airbag and SRS systems, Alarm immobiliser, Heater and Air-conditioning control, Key coding and even Battery charging control.

Here at Castle Performance we have the very latest software and equipment to diagnose the fault on your car, and the knowledge to back it up..

More often than not the cause of the problem with these systems is either wiring or a sensor fault and it’s not as easy as just resetting the warning light. If the cause is not fixed then the light will come back as soon as that system is used again.
