When warning lights start flashing or messages appear on you cars display/ instrument panel panic can strike. Most owners refer to the cars manual only to find a very general explanation of the possible faults then usually just a message to contact the vehicle dealer for testing.

Quite often the warning symbols illuminate due to low fluids or service items needing to be replaced / topped up and others to indicate a system malfunction in a particular area such as engine/brakes/steering etc. these faults are usually caused by sensor failure or wiring faults in the system.

Modern cars have a wealth of electronic control units and sensors fitted which operate without fault for years but it only takes a small change in the system for a fault to be logged and the dreaded warning light to flash at you.

If the fault is not repaired the vehicle control units can disable that system or limit for example the engines power or gearbox selection so as to reduce possible damage to other components not linked to the fault.

We often see owners who have been given a possible cause of the fault and replaced parts only to find the fault is still present. This method of repair is not recommended unless you have money to waste as most electronic parts are non returnable even if you just opened the box.

  Using the correct diagnostic process and equipment is essential for fast accurate repairs to be carried out. sometimes a little knowledge can be at best costly and at worst dangerous. The modern electronic control unit (ECU) is a robust but sensitive unit and incorrect testing can result in damage to a perfectly good unit.
 

If you don’t know the system or do not have the correct equipment do not attempt ANY testing or repairs !!!!

Our diagnostic fees start at only £57.50 for reading codes/resets.

Fast diagnostics helps to eliminate the use of unneeded parts / excessive labour charges.
