Should I check the MOT history before buying a 2020 Audi Q3 S Line 40 TFSI Quattro S A?

The 2020 Audi Q3 S Line 40 TFSI Quattro is a genuinely reliable performer, with a 94.9% first-time MOT pass rate that sits well above the UK average of 80%—this is the kind of consistency you want to see from a premium compact SUV. The 8.2% rate of dangerous defects is moderate and not a red flag, and only 0.19 failures per vehicle on average suggests these cars are built to last.

At 27,997 miles average, these vehicles are running light for their age, which partly explains why they're passing so cleanly; however, even as mileage climbs, the solid engineering should hold up. The 3.3 advisories per car are typical wear-and-tear issues rather than structural concerns, so before you buy, get a full service history check and have a mechanic inspect the suspension and brakes to catch any early wear before it becomes expensive.

The 2020 Audi Q3 S Line 40 TFSI Quattro S A passes its MOT first time more often than most UK vehicles (95.6% 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 95.6% 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 3.3 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 958 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.
