The 2020 Audi A3 e-tron 40 S-A passes its MOT first time 85.6% of the time, which beats the UK average of 80% and suggests a generally reliable car—though the 24.4% that have experienced dangerous defects is a genuine concern and worth investigating during a pre-purchase inspection. Nearly all models in this cohort are hybrid electric, and they're holding up well across the board with that same strong pass rate.

At just under 38,000 miles on average for a four-year-old car, these vehicles are running at typical mileage, and owners are averaging 0.52 failures per MOT with 2.9 advisories—a modest maintenance load that reflects the hybrid's relative simplicity. Before buying one, ask the seller for full service history and get an independent hybrid battery health check, since that's where future costs can surprise you.

The 2020 Audi A3 E Tron 40 S A passes its MOT first time at roughly the UK average rate (87.9%) — solid but worth checking this vehicle's history carefully.

⚠️ 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 87.9% 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 2.9 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 1,092 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.
