Pre-MOT Inspection Checklist for BMW 330 Owners

These checks follow this BMW 330's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW 330.

• 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 wipers and washers — “wipers blade defective”

  Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.

Where the BMW 330 is most common

Across every 330 model year on record (2001–2021): 37,730 BMW 330 cars tested in a recordable postcode area, across 66,456 tests. Birmingham (B) has the most, with 1,453 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most BMW 330 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 →
