Pre-MOT Inspection Checklist for BMW M4 Competition Owners

These checks follow this BMW M4 Competition's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW M4 Competition.

• the windscreen — “windscreen damaged”

  Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.

• the tyre tread — “tread depth below requirements of 1.6mm”

  Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.

• the number plates — “registration plates does not conform to the specified requirements”

  Check both plates are present, legible and correctly spaced, with the postcode of the supplier and the BS AU 145e mark. A private plate in the wrong style is a fail before the car is even looked at.

Derived from the DVSA failure strings testers recorded for the BMW M4 Competition. A check that finds nothing means the item is likely fine, not that the test is guaranteed.

The twenty areas with the most BMW M4 Competition cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →
