Should I check the MOT history before buying a 2015 Audi S3?

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 2015 Audi S3?

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 2015 Audi S3?

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 2015 Audi S3 is a reliably built car, with a 93.3% first-time MOT pass rate well above the UK average of 80%—this is a genuinely strong result. The dangerous defect rate of 16.3% is worth noting for a buyer, though not alarming, suggesting occasional serious issues rather than a pattern.

At just under 50,000 miles on average, these cars have been sensibly used, and the low failure count of 0.61 per vehicle reflects that care. However, advisories run high at 5.5 per car, so budget for maintenance items like brakes, suspension, and wear parts—have a pre-purchase inspection focus on these known weak points.

We have limited data for the 2015 Audi S3 — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 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.
