Engine diagnostics

Warning light on? We read the fault codes, find the cause and tell you straight.

Engine diagnostics at your door

A warning light can mean anything from a loose fuel cap to a failing sensor. A fault code on its own rarely tells the full story — so we read the codes, then test the parts behind them to find the actual cause.

You get a clear explanation of what’s wrong, how urgent it is and what it will cost to fix. Often we can carry out the repair there and then.

We cover West London, Surrey & Berkshire — see where we work. Call 07470 794111 for a quick quote.

Common questions

Is it safe to drive with the engine light on?

A steady light usually means get it checked soon; a flashing light means stop driving as soon as it’s safe, as it can signal a misfire that damages the engine. Call us and we’ll advise.

Can you diagnose hybrids?

Yes, we work on petrol, diesel and hybrid vehicles.

Will you just clear the code?

No. Clearing a code without fixing the cause just brings the light back. We find the fault first.
