Frequently Asked Questions
Our diagnostic process connects professional scanning equipment to your vehicle's OBD port to read stored fault codes from the engine management system and other control units. We then review live sensor data to pinpoint the root cause of the issue before recommending a repair.
A diagnostic check identifies the fault causing the warning light — it does not fix the underlying issue itself. Once we have identified the fault code and confirmed the cause, we will advise on the required repair and provide a quote before any work is carried out.
An engine management light (EML) can be triggered by many things including a faulty oxygen sensor, a loose fuel cap, a catalytic converter issue, spark plug problems or a DPF fault. A diagnostic check will identify the exact cause.
A standard diagnostic check typically takes 30 to 60 minutes. More complex intermittent faults may require additional time for live data monitoring and testing. We will advise on timing when you book.
