Common questions
What does it mean when my check engine light comes on?
It could be anything from a minor sensor fault to a more serious issue. A diagnostic scan reads the exact fault code stored by the car's computer, so we know precisely what's wrong instead of guessing.
How long does a diagnostic check take?
A standard scan and explanation usually takes 20–40 minutes, done on your driveway with a professional OBD scanner.
Can you fix the fault on the same visit?
Often, yes. Simple faults can sometimes be resolved there and then. For bigger jobs, I'll give you a clear quote and can usually book the repair in quickly.
Do you clear the fault code after fixing the issue?
Yes. Once the repair's done, I clear the code and re-test to confirm the warning light stays off.
