Diagnostics FAQs
How long does a diagnostic take?+
A standard scan and report takes around 45–60 minutes. Intermittent electrical faults can take longer and we will always agree extra time with you first.
Do you cover German cars?+
Yes — BMW, Mercedes, Audi, VW, Porsche and Mini are day-to-day work for us, alongside Japanese, Korean, French and British makes.
Is the diagnostic fee refundable?+
If you go ahead with the repair, the diagnostic fee comes off the final invoice.
Can you clear the light without fixing it?+
We can, but we will not do so without explaining the fault first — clearing a code does not repair the cause and it will normally return.
