Can you tell me what the warning light means?

We read the fault codes, review live sensor data, and carry out targeted tests to confirm what actually triggered the light. A code read alone does not always identify the root cause — we test until we do.

How much does a diagnostic check cost?

Our diagnostic check starts from £60. If you go ahead with the recommended repair in the same visit, we discuss offsetting the fee against the job cost. We confirm everything before work starts.

Do you diagnose faults beyond warning lights?

Yes. Unusual noises, poor fuel economy, misfires, rough idle, and intermittent faults can all be investigated. We build a test plan around your symptoms rather than just plugging in a scanner and guessing.
