Warning light on? Car running poorly? Get clear answers from a BMW & MINI specialist.

At Clifton’s Auto Repairs Ltd, we combine practical workshop experience with genuine BMW ISTA diagnostic software—the same diagnostic platform used by BMW main dealers. Through BMW’s official online Aftersales System (AOS), we access up-to-date manufacturer technical information, repair procedures and diagnostic support.
What our diagnostic service includes
- Understanding your concern: We discuss the symptoms and when they happen, helping us target the investigation.
- Electronic system checks: We scan the vehicle’s control units, assess fault codes and investigate relevant warning messages.
- Live-data analysis: We examine how sensors and components are performing and compare readings with expected values.
- Targeted testing: We use BMW guided test procedures alongside practical electrical and mechanical checks to trace the cause.
- Road testing where needed: We investigate faults under the conditions in which they occur, where safe and practical.
- Clear findings and advice: We explain what we find, recommend the next steps and discuss costs before additional work.
We investigate engine running problems, loss of power, starting faults, emissions issues, transmission concerns, ABS warnings and electrical faults. Coding, programming and software updates are also available where required and supported by the vehicle.
Our aim is to find the cause, reduce unnecessary parts replacement and help you make an informed repair decision. Some intermittent or complex faults may require further investigation, which we will discuss with you.
