Pre-MOT Inspection Checklist for BMW 428 Owners

These checks follow this BMW 428's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW 428.

• 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 shock absorbers — “shock absorbers has a serious fluid leak”

  Press down hard on each corner of the car and let go. It should settle in one bounce; if it keeps rocking, or you can see oil weeping down a shock absorber, that is the fault a tester will find.

• 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.

Derived from the DVSA failure strings testers recorded for the BMW 428. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
