Moderate sample. 404 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This Q7 is a reliable performer: it hits a 91% first-time MOT pass rate, comfortably above the UK average of 80%, with only 10.2% of vehicles ever showing a dangerous defect—a reassuringly low figure for a large premium SUV. The petrol engine variant (which accounts for nearly all of these) maintains that strong 90.9% pass rate.

At 33,607 miles median for a 2021 model, these Q7s are running well within normal expectations, and the low failure rate of 0.25 per vehicle suggests owners aren't facing major mechanical surprises. The 1.9 advisories per car flag the typical wear items you'd expect on a complex luxury SUV, so when you're viewing one, budget for minor attention to suspension and trim components rather than anything structural—a pre-purchase inspection should be straightforward to complete.

The 2021 Audi Q7 Sln Blk Ed 55tfsi MHEV Qt A passes its MOT first time more often than most UK vehicles (92.4% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

✅ Good baseline reliability. A 92.4% 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 1.9 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.
