The 2015 Audi TT passes its first MOT attempt 90.4% of the time, well ahead of the UK average of 80%, but there's a significant caveat: nearly a third of these cars (31.2%) have recorded a dangerous defect at some point, which is a genuine buyer concern. Petrol models perform noticeably better than diesels, with a 91.3% pass rate versus 88.5%, suggesting the diesel version carries more risk.

At just over 40,000 miles median mileage, these nine-year-old Audis are running relatively low, which explains the strong pass rates. However, owners are dealing with nearly 8 advisories per car on average, pointing to wearing trim, sensors, and minor systems that need budgeting for—check suspension components and brake wear closely on any example you're viewing.

The 2015 Audi Tt has a decent first-time pass rate (90.4%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 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 90.4% 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 7.9 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.

These stats describe 8,807 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.
