Diagnostics / Warning Lights

A warning light on the dashboard is your car's way of saying "something's not right" — but it rarely tells you exactly what. Modern cars run dozens of sensors and control modules, and a single light can have a dozen possible causes. Guessing gets expensive fast, which is why we diagnose properly.

Using professional scan tools, we read the fault codes stored in your car's systems, interpret them against what the car is actually doing, and pinpoint the real cause. That means you only pay to replace the part that's genuinely at fault — not a string of parts on a hunch.

Lights worth acting on

• Engine management (EML): could be minor or serious — best checked promptly.
• ABS: your anti-lock braking may not work as intended.
• Battery / charging: often the alternator or battery on its way out.
• DPF: a blocked diesel particulate filter needs attention before it gets costly.
• Airbag / SRS: a safety system that may not deploy when needed.

A red light usually means stop and call us; an amber one means get it checked soon. Either way, don't ignore it and hope it goes away — it rarely does. Pop in or call 01282 424262 and we'll plug in and find out what your car is trying to tell you.
