Expert verdict

Tyres: 3.0× the national share

Tyres make up 59.8% of everything recorded on the 2021 BMW 330, against 19.8% nationally — 40.0 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.

Where the BMW 330 is most common

Across all 330 model years 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 →

Before your test

Three checks worth doing on a 2021 330

These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.

  1. Check the tyre tread 1.8% of tests

    “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.

  2. Check the suspension joints 1.1% of tests

    “ball joint excessively worn”

    With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.

  3. Check the windscreen 0.9% of tests

    “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.

Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

What it costs to get a 2021 330 through its MOT

Across the 10 items that are recorded most often on this model, the average repair comes to £42–£95 — and 0% of those repairs are parts that cost under £30.
