Diagnostics & warning lights

A warning light tells you something needs looking at, not which part to replace. We test properly before recommending any repair, so you don't pay for guesswork.

Diagnostic check from around £50.Usually 45–90 minutes.

What's included

  • Fault codes read across the relevant systems
  • Live data and circuit testing, not just a code print
  • A plain-English explanation of the cause
  • A repair quote before anything is ordered

Prices are guidance, not a quote. Some of the fee may be credited if you go ahead with the repair. We inspect the car and confirm the price before any work starts.

Common questions

Can you fix it from the warning light alone?

No. The light points to a system; the cause could be a sensor, wiring, a leak or a mechanical fault. We test before quoting.

Is it safe to drive with the light on?

A red light or a flashing engine light means stop and get advice. A steady amber light usually means book a check soon rather than ignore it.
