Is the 2018 A7 getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 90.3% +2.2 vs same-age |
|
| 2024 | 89.3% +3.1 vs same-age |
|
| 2025 | 89.6% +4.9 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 2018 Audi A7 reliable?
2018-registered examples passed 89.8% of their MOT tests (4,127 tests, 2023–2025), +3.4 points versus all UK cars registered in the same year. At roughly 8 years old with a median 53,708 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2018 A7?
The median tested example shows 53,708 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.
Should I buy the petrol or diesel 2018 A7?
In this cohort petrols pass 93.4% of tests against 88.9% for diesels. Mileage and use can explain part of that gap, so treat it as a reason to inspect DPF and emissions history, not a fuel-type verdict.
