Pre-MOT Inspection Checklist for BMW 523 Owners

These checks follow this BMW 523's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW 523.

• 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 — “headlamp lens slightly defective”

  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 suspension joints — “ball joint dust cover severely deteriorated”

  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.

Derived from the DVSA failure strings testers recorded for the BMW 523. A check that finds nothing means the item is likely fine, not that the test is guaranteed.

Where the BMW 523 is most common

Across every 523 model year on record (2000–2013): 2,533 BMW 523 cars tested in a recordable postcode area, across 5,529 tests. London (E) has the most, with 107 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 523 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 →
