Pre-MOT Inspection Checklist for BMW X4 M40D Owners

These checks follow this BMW X4 M40D's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW X4 M40D.

• 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.

• 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.
