Diagnostics
Dealer-level fault finding using factory-grade BMW & MINI diagnostic systems — so the root cause is found and fixed, not guessed at and parts thrown at it.
What this covers
A generic code reader tells you a fault exists. Dealer-level diagnostics tell you why. BM Pro uses factory-grade equipment to read and program every control module exactly as the main dealer can.
We combine fault memory, live data and guided test plans to trace intermittent and complex faults — drivability issues, electrical gremlins, warning lights and emissions problems — to their true source.
You receive a clear written report explaining what we found, what it means and a fixed quote for any repair. No jargon, no fishing expedition.

Frequently asked
How much is a diagnostic?
A fixed diagnostic fee applies, confirmed when you book. If you proceed with the repair, we'll always tell you up front how the diagnostic cost is treated.
Another garage couldn't find the fault — can you?
Often, yes. Specialist equipment plus BMW & MINI-only experience is exactly why customers come to us with faults others have given up on.
Can you code and program modules too?
Yes — see our coding & programming work. We can retrofit, code and update modules at dealer level.
Is it safe to drive with the warning light on?
It depends on the fault. If a red warning light is showing, stop driving and call us. Amber lights should still be checked promptly.
