Diagnostics & warning lights

A warning light tells you something is wrong, not what. We scan, test and confirm the real cause, then explain it in plain words and quote before we fix.

Signs you may need this

  • Check-engine light on or flashing
  • Rough idle or stalling
  • Engine hard to start
  • Worse fuel economy than usual
  • ABS, airbag, battery or temperature light on
  • A new smell, smoke or unusual noise

If a red oil-pressure or engine-temperature light comes on, pull over safely, switch the engine off and contact us for advice before driving further.

What we check

  • Stored and pending trouble codes
  • Live data from the engine and sensors
  • Hoses, wiring, connectors and fluid levels
  • A test of the suspected part before we recommend replacing it

How it works

  1. We listen to what you have noticed and scan the car.
  2. We test to confirm the cause, not just read the code.
  3. You get the findings and a written estimate. You approve, then we fix.

Diagnostics & warning lights FAQ

Can you just read the code and tell me what to replace?

A code points to a system or a circuit, not always to a faulty part. Replacing parts from a code alone can waste money, so we test first to confirm the cause.

Is it safe to drive with the check-engine light on?

A steady light is often not an emergency, but get it checked soon. A flashing light means reduce speed and avoid heavy loads until it is looked at. A red oil-pressure or temperature light means stop safely.

Why does the warning light come and go?

Some faults only show up in certain conditions, such as cold starts or heavy load. Tell us when it happens. Faults that come and go can take longer to trace.
