2021 Audi A3 Technik 30 TFSI
CarHunch analysed 895 real MOT records for the 2021 Audi A3 Technik 30 TFSI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Audi A3 30 TFSI is significantly more reliable than the UK average, with a 93.5% first-time pass rate well ahead of the 80% benchmark—and a low 6% rate of dangerous defects suggests serious mechanical issues are uncommon. At under 31,500 miles on average, these are young cars with minimal wear, which explains why failures are rare at just 0.19 per vehicle. The 1.8 advisories per car are routine maintenance flags rather than red flags, typical for petrol engines of this age and mileage. If you're considering one, a pre-purchase inspection remains sensible, but the MOT data points to a solid, well-engineered small saloon with few hidden nasties.
What to check before buying a 2021 Audi A3 Technik 30 TFSI
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
