BMW 5 Series MOT pass rate & common failures

At a glance

Pass rate, adjusted for age and mileage

The 5 Series is 9.7 percentage points above the national pass rate once age and mileage are accounted for, which is well above average. The unadjusted figure is 79.7%; the difference is what the age and mileage of this model’s fleet was hiding.

How wear changes the picture

5 Series pass rate by age and registration year

How often the BMW 5 Series passes at each age, with the years those cars were first registered. Tests are from 2025, so a car aged 3 to 5 was first used in 2020–2022.

Read this as an age curve rather than a verdict on particular model years. Nearly every car passes less often as it gets older, so a newer 5 Series outscoring an older one says more about wear than about how that year’s cars were built. Bands holding too few tests to be meaningful are omitted rather than shown as a rate.

Common questions

Is the BMW 5 Series reliable?

On MOT evidence the BMW 5 Series is well above average. It passes 82.0% of tests once age and mileage are accounted for, against a national average of 72.3%, which ranks it 38 of 262 models with enough data for a fair comparison. This measures how often the car meets the MOT standard, not how often it breaks down or what a repair costs.

What is the most common MOT failure on a BMW 5 Series?

The item recorded most often is "Tyre tread depth not in accordance with the requirements", which appears in 16.4% of failed BMW 5 Series tests. Because one failed test can list several items, these shares do not add up to 100%.

What do testers most often warn about on a BMW 5 Series?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 25.4% of all BMW 5 Series tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a BMW 5 Series usually have at its MOT?

The average odometer reading recorded at test is 105,911 miles. This is the mileage across all tested examples of every age, not an annual figure, so treat it as a description of the fleet rather than a target for one car.

Which BMW 5 Series years are the most reliable?

Going by MOT pass rate, BMW 5 Series cars first registered 2020–2022 do best at 87.5%, and those registered 2010 and earlier do worst at 69.9%. But that ordering is mostly age, not build year: almost every model passes less often as it wears, so the newest cars top this list whatever they are. A specific year looking strong here means little on its own; the failure items above, and the individual car's own MOT history, tell you far more.

Does a BMW 5 Series get harder to pass as it ages?

Yes. At 3 to 5 years old, 87.5% of BMW 5 Series tests pass. By fifteen years or more, that falls to 69.9%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most BMW 5 Series models petrol or diesel?

Of the BMW 5 Series cars tested, 72% are diesel, 14% are petrol, 9% are hybrid. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

How this was worked out

Method and limits

Figures come from the DVSA anonymised MOT testing dataset, published under the Open Government Licence. Only class 4 initial tests are counted: retests are excluded so a car appears once, and abandoned tests are excluded entirely. The adjusted rate is directly standardised across twenty-five age and mileage bands and reweighted onto the national distribution, so this model is compared against cars that have lived a similar life rather than against a younger or lighter-used fleet.

An MOT measures whether a car met a legal standard on the day. It is not a breakdown record, a service history or a running-cost estimate, and a pass rate is a property of a fleet rather than a prediction about one car.
