Pre-MOT Inspection Checklist for BMW M5 Cs Owners

These checks follow this BMW M5 Cs's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW M5 Cs.

  • the lights — “headlamp aim too low”

    Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

  • 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.

  • 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.
