2014 Audi A4 S Line Black Edition TDI

CarHunch analysed 414 real MOT records for the 2014 Audi A4 S Line Black Edition TDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2014 Audi A4 S Line TDI diesel has a first-time pass rate of 73.2%, which is noticeably below the UK average of 80%, suggesting these cars are slightly more prone to MOT failures than typical. The good news is that dangerous defects are virtually absent (0%), so while you might need repairs before passing, you're unlikely to encounter safety-critical issues.

At nearly 95,500 miles on average, these are well-used examples, yet they're averaging only 0.45 failures per test—a manageable tally that reflects typical wear rather than chronic problems. If you're considering one, get a pre-purchase inspection that focuses on the diesel engine, emissions system, and suspension components where most failures cluster, rather than worrying about structural safety.

What to check before buying a 2014 Audi A4 S Line Black Edition TDI

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.
