Advisories to look for in a Mini Cooper's MOT history

An advisory is a tester's warning that something is wearing but has not failed yet. These are the ones written most often on the Mini Cooper, per 1,000 tests. If the car you are looking at has one of these, ask whether it has been fixed since.

  • Tread depth: worn close to legal limit/worn on edge224.7
  • Tyres: slightly damaged/cracking or perishing169.6
  • Brake discs: worn, pitted or scored, but not seriously weakened102.6
  • Engine oil leaks: leak, but not excessive69.5
  • Brake pads: wearing thin66.7
  • Sub-frame: corroded but not seriously weakened65.3

Checking a used Mini Cooper before you buy

Against cars of the same age, the Mini Cooper fails more often than average on engine, emissions and leaks. Start there.

  • Engine, emissions and leaks

    Start the car from cold and watch the exhaust for smoke, look underneath for oil or fuel leaks, and make sure the engine warning light comes on with the ignition and goes out once the engine runs.

Averages only take you so far. The specific car's MOT history shows whether it has already failed on any of these, how often advisories were ignored, and whether the mileage climbs steadily from test to test. Read our guide to reading a car's MOT history before you go to view it.

Fuel mix of the Mini Cooper cars tested: Petrol 81%, Diesel 15%. Average age at test 10.3 years, average recorded mileage 61,300.

Which Mini Cooper year has the best MOT record?

Does this tell me whether a particular Mini Cooper will pass?

How these figures are calculated

Source: DVSA Anonymised MOT tests and results, 2025 release. We count first tests of cars and small vans (class 4) aged 3 to 20, so a car that fails and is retested is counted once. A failure includes faults fixed and passed within the same visit. The same age average weights the national failure rate for each age by how many Mini Cooper cars of that age were tested, so a model is never penalised for having an older fleet. Make and model are as recorded at the test; trim levels are combined. Full method and rankings.
