Engine Management Light On

For check engine lights, MIL lights and dashboard warnings that need a sensible first step.

Cowbridge, Llantwit Major, Barry and Bridgend

Do not just clear it and hope

The MIL or check engine light can cover anything from a minor emissions warning to a fault that risks damage. The first job is to understand what the car has recorded and whether it is safe to keep driving.

We start with the warning message, scan data and symptoms, then explain whether the vehicle needs servicing, a specific repair or deeper fault-finding.
