Pre-MOT Inspection Checklist for BMW 318D Owners

These checks follow this BMW 318D's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW 318D.

• 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 lights — “malfunction indicator lamp inoperative or indicates a malfunction”

  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.
