Here at Maldwyn Williams Ltd we’ve invested in main dealer diagnostics covering the following manufacturers: BMW/Mini (ISTA), VW, Audi, Seat, Skoda (ODIS), Citroen and Peugeot (DIAGBOX), and Jaguar Land Rover (SDD Pathfinder).

Technology advances at a rapid pace, and we are diagnostic specialists supported by Autologic and we’re also affiliated with ZF Aftermarket Protech.

What is a Car Diagnostic Test?

A car diagnostic test identifies problems with a malfunctioning vehicle. It’s an accurate assessment carried out by a technician using a diagnostics machine. Using specialized software, car diagnostic tools detect faults in a car’s engine or elsewhere, through the use of microchips, sensors, and built-in processors.

The computer scans the vehicle’s onboard computer, identifying any diagnostic trouble codes, and also service notifications issued by your vehicle’s manufacturer.

What faults do diagnostics identify?

Diagnostic tests commonly identify engine problems, problems with brakes, exhausts and other major components, as well as issues with fuel injectors, airflow and coolant, throttle, ignition coils, and transmission problems.
As well as expert diagnostic testing, we offer a full range of services and repairs, all carried out to the highest standard.
