Should I check the MOT history before buying a 2017 Audi A3?

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 2017 Audi A3?

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 2017 Audi A3?

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 2017 Audi A3 passes its MOT first time in 90.3% of cases, comfortably ahead of the UK average of 80%, which is genuinely encouraging. However, nearly 29% of these cars have recorded a dangerous defect at some point, which is substantially higher than typical and warrants a pre-purchase inspection by a trusted mechanic. Petrol versions edge out diesels on reliability (90.9% vs 89.2% pass rate), though both are solid performers.

At a median mileage of just over 40,000 miles for a seven-year-old car, these A3s are relatively well-used but not worn out. The average car picks up 5.9 advisories per test and around 0.75 failures, suggesting minor maintenance issues crop up regularly rather than major ones. Before you commit, get a full history check and have any used A3 inspected by an Audi-familiar garage, especially focusing on the electrical and braking systems where dangerous defects have been recorded.

The 2017 Audi A3 has a decent first-time pass rate (90.3%), 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 90.3% 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 5.9 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 35,589 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.
