Audi A4 (2013)

19,145 real MOT outcomes analysed • 84.6% first-time pass rate

2013 Audi A4

CarHunch analysed 19,145 real MOT records for the 2013 Audi A4. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2013 Audi A4 passes its MOT first time at 84.6%, comfortably above the UK average of 80%, which is a solid endorsement—but nearly 4 in 10 owners have encountered a dangerous defect at some point, so structural and safety issues aren't uncommon enough to ignore. Petrol versions perform notably better (87.8% pass rate) than diesels (84.0%), suggesting the petrol engines are more robust long-term.

With a median mileage of 81,307 miles for an 11-year-old car, these are well-used but not exceptional runners, and the average of 1.82 failures per vehicle indicates most issues are manageable rather than catastrophic. Before buying, get a thorough pre-purchase inspection that explicitly covers suspension, brakes, and exhaust systems—these A4s rack up 12.4 advisories on average, and many cluster around wear items that can spiral into costly repairs if left unchecked.

What to check before buying a 2013 Audi A4

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.
  • ⚠️ 38.5% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
