Is the 2020 A5 getting worse?

Pass rate of 2020-registered cars across recent test years:

Test year	Pass rate
2023	89.2% -1.6 vs same-age
2024	88.4% -1.6 vs same-age
2025	89.1% +0.2 vs same-age

The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

FAQs

Is a 2020 Audi A5 reliable?

2020-registered examples passed 88.9% of their MOT tests (6,674 tests, 2023–2025), -1.0 points versus all UK cars registered in the same year. At roughly 6 years old with a median 31,488 miles, condition now varies car by car — always check the individual MOT history.

What mileage is too high for a 2020 A5?

The median tested example shows 31,488 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
