Engine Light, Limp Mode Or Poor Running

For cars with warning lights, hesitation, rough running, smoke or repeat engine fault codes.

Cowbridge, Llantwit Major, Barry and Bridgend

A code tells us where to look, not what to buy

An engine fault code tells us where the ECU has seen a problem. It does not automatically prove which part should be fitted. We compare the code with how the car drives, live data and workshop checks.

This is the starting point for engine lights, limp mode, hesitation, poor running, sensor faults, boost faults and repeat codes. If the issue is more specific, we will route it to misfire, DPF, EGR, AdBlue or power-loss checks.
