Should I check the MOT history before buying a 2018 Audi Q8?

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 Q8?

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.

The 2018 Audi Q8 passes its MOT at 80.9%, which is fractionally above the UK average of 80%—a reassuring sign of baseline reliability. Only 10.5% of these vehicles have ever recorded a dangerous defect, so serious safety issues are not a widespread concern for the model.

At 42,802 miles median, these Q8s are running at a typical mileage for their age, suggesting owners are using them normally rather than subjecting them to extreme duty. The average of 0.37 failures per vehicle is very low, though 3.5 advisories per test points to minor wear items cropping up—expect to budget for small maintenance jobs, particularly around suspension and trim components, before buying one used.

The 2018 Audi Q8 passes its MOT first time more often than most UK vehicles (93% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 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 93% 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 3.5 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 724 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.
