How reliable is the Audi SQ5 compared with other cars?

We do not publish a comparison for the Audi SQ5, because the cars of this model that have been tested do not cover a wide enough range of ages and mileages. Its raw pass rate is 90.9% across 2,121 tests, but comparing a raw rate between models mostly ranks them by how new they are rather than how good they are. The failure and advisory patterns further down the page are still drawn from real tests and are worth reading.

What is the most common MOT failure on a Audi SQ5?

The item recorded most often is "Tyre tread depth not in accordance with the requirements", which appears in 20.2% of failed Audi SQ5 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 Audi SQ5?

The most common advisory is "Tyre tread depth not in accordance with the requirements", noted on 18.6% of all Audi SQ5 tests. An advisory is not a failure: it flags something that will likely need attention before the next test.

What mileage does a Audi SQ5 usually have at its MOT?

The average odometer reading recorded at test is 53,129 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.

Does a Audi SQ5 get harder to pass as it ages?

Yes. At 3 to 5 years old, 93.0% of Audi SQ5 tests pass. By 12 to 14 years, that falls to 76.5%. Nearly every model follows this pattern, which is why comparing raw pass rates between models is misleading unless age is accounted for.

Are most Audi SQ5 models petrol or diesel?

Of the Audi SQ5 cars tested, 98% are diesel, 2% are petrol. Fuel type affects which items tend to fail, particularly emissions and exhaust components.

Audi SQ5 MOT pass rate & common failures

From 2,121 recorded MOT tests of the Audi SQ5, published by DVSA.

Data updated 29 July 2026

Quick answer

Across 2,121 MOT tests, 90.9% of Audi SQ5 tests ended in a pass. This figure is not adjusted for age or mileage, so it is not a reliability ranking: the Audi SQ5 fleet does not yet cover a wide enough spread of ages and distances to compare it fairly against other models. Its most commonly recorded failure is tyre tread depth not in accordance with the requirements, which appears in 20.2% of failed tests. Cars of this model average 53,129 miles on the odometer when tested.

Recorded pass rate

90.9%unadjusted, not comparable2,121 tests

We are not publishing a ranking for the SQ5. The examples tested do not cover a wide enough spread of ages and mileages to compare it fairly, and an unadjusted pass rate mostly sorts models by how recently they were bought rather than how well they were built. The failure and advisory patterns below come from the same 2,121 tests and are worth reading on their own terms.

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. No adjusted rate is shown because this model's tested examples do not cover enough of the national age and mileage range for standardisation to mean anything.

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.
