Advisories to look for in a BMW 5 Series'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 BMW 5 Series, 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 edge295.4
- Brake discs: worn, pitted or scored, but not seriously weakened77.2
- Brake pads: wearing thin74.1
- Suspension arms: pin or bush worn but not resulting in excessive movement66.4
- Shock absorbers: has light misting of oil60.9
- Engine oil leaks: leak, but not excessive50.1
Checking a used BMW 5 Series before you buy
Against cars of the same age, the BMW 5 Series fails more often than average on wheels. Start there.
Wheels
Look for damaged rims, missing wheel nuts and cracked alloys, particularly on the inside edge where kerb damage hides.
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 BMW 5 Series cars tested: Diesel 75%, Petrol 10%, Hybrid 9%, Diesel hybrid 6%. Average age at test 10.5 years, average recorded mileage 104,300.

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 BMW 5 Series 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.
