Is it safe to drive with the EML on?

A steady amber EML usually means you can drive cautiously to a workshop. A flashing EML or a red warning means stop as soon as it’s safe — misfires can damage the catalytic converter.

How long does an engine diagnostics session take?

Basic fault-code read and triage can be 20–40 minutes. In-depth testing (live data, smoke/leak testing, scope work) typically ranges 60–120 minutes depending on the fault.

Will you just clear the light?

We never simply clear codes. We diagnose the root cause, explain findings, provide a repair estimate, and only reset once the underlying fault has been addressed.

How much does EML diagnosis cost?

We offer fixed-price initial diagnosis, then agree any deeper testing with you first. You’ll always know costs before we proceed.

What if the light comes back after repairs?

Our work is guaranteed. If the same fault returns within the warranty period, bring the car back and we’ll re-check it. Some vehicles can present multiple related faults; we’ll advise clearly.
