Should I check the MOT history before buying a 2018 Audi Q5?

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 Q5?

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 Q5?

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 Q5 is a reliable proposition, with an 88.7% first-time pass rate that beats the UK average of 80%, and petrol variants perform slightly better at 90.2% versus diesels at 87.4%. However, 15.5% of these cars have recorded a dangerous defect at some point, which is worth factoring into your inspection checklist.

These Q5s are running modest mileage for their age—a median of 45,578 miles suggests careful use—and most pass with only 0.54 failures per vehicle on average, though advisories average 4.7, indicating minor wear items rather than structural problems. Before purchasing, have a pre-buy inspection focus on the common advisory areas (likely suspension and brake components) and request full service history to confirm maintenance has kept pace with that relatively low mileage.

The 2018 Audi Q5 passes its MOT first time at roughly the UK average rate (91.4%) — 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 91.4% 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 4.7 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 13,659 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.
