Amber and Red Warning Lights
An amber light usually requires timely investigation. If a red warning appears, the engine runs badly, loses power, overheats or makes an unusual noise, stop safely and seek professional advice before continuing.
How We Diagnose the Fault
Diagnosis may combine a code scan with live data, visual checks and targeted testing. The correct approach depends on the fault and whether the vehicle is petrol or diesel.
