Warning light diagnostics

We investigate dashboard warnings and stored vehicle faults using diagnostic equipment and technical testing.

Why it mattersA warning light tells you something needs attention — not which component needs replacing. Accurate diagnosis avoids unnecessary parts.

Mechanical fault diagnosis

Noises, vibrations, overheating, poor running and loss of power investigated properly.

Why it mattersMany mechanical issues share the same symptoms. Correct diagnosis reduces guesswork.

FAQs

Diagnostics questions, answered

How long does diagnostics take?

It depends on the fault. Straightforward checks are usually completed the same day; intermittent electrical faults can take longer. We'll give you a realistic timescale when you book.

Is diagnostics just plugging in a computer?

No. Codes point us in a direction. Confirming the fault takes live data, physical testing and technician judgement.

Will you repair the fault afterwards?

In most cases yes. We'll explain what we found and what the repair involves before anything is authorised.

Can diagnostics be covered by my warranty?

Sometimes. Cover varies by provider and policy, so we'll help you check before work begins.

What if you cannot reproduce the fault?

We'll tell you honestly, share what we tested and recommend the most sensible next step rather than replacing parts speculatively.

Do I have to approve the repair?

Yes. No repair work proceeds without your approval, and where relevant, the approval of your warranty provider or insurer.
