Should I check the MOT history before buying a 2018 Audi A7?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2018 Audi A7?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2018 Audi A7?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2018 Audi A7 passes MOT at 83.9%, modestly above the UK average of 80%, suggesting reasonably solid reliability overall—though 18.4% have experienced a dangerous defect, which is worth noting if safety is a primary concern. Petrol variants perform noticeably better at 87.7% pass rate versus 83.0% for diesel, so fuel type is a meaningful factor in your decision.

At nearly 47,500 miles on average, these cars have typical mileage for their age, and the 0.52 average failures per vehicle suggests most get through without major structural issues. However, the 3.7 advisories per MOT indicate emerging wear—mainly minor niggles—so budget for preventative maintenance and have a pre-purchase inspection focus on the suspension, brakes, and electrical systems where German prestige cars commonly rack up advisory notices.

The 2018 Audi A7 passes its MOT first time at roughly the UK average rate (90.9%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 90.9% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 3.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,567 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
