FREQUENTLY ASKED QUESTIONS
How long does a diagnostic check take?
Most diagnostic sessions take 30 to 60 minutes depending on the fault. Complex issues may need longer live data testing.
Do you diagnose BMW and Mercedes cars?
Yes. We specialise in German cars and use equipment capable of reading manufacturer-specific fault codes.
Will you tell me what needs fixing before any work starts?
Always. We explain the fault, the likely cause and the cost before we carry out any repairs.
Can diagnostics find intermittent faults?
Yes. Live data logging and road testing help us track down faults that do not show up on a quick scan.
Do I need a diagnostic before a service?
Not always. If your car is running normally, a service is enough. Diagnostics are for warning lights or known faults.
