Pre-MOT Inspection Checklist for BMW 1 Series Owners

These checks follow this BMW 1 Series's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW 1 Series.

• 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 lights — “position lamp not working”

  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.

• 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.

Where the BMW 1 Series is most common

Across every 1 Series model year on record (2004–2020): 131,581 BMW 1 Series cars tested in a recordable postcode area, across 273,487 tests. Birmingham (B) has the most, with 4,682 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 1 Series 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 →
