Audi A4 S Line Black Edition TDI (2013)
2013 Audi A4 S Line Black Edition TDI
CarHunch analysed 542 real MOT records for the 2013 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 2013 Audi A4 S Line Black Edition TDI struggles at MOT compared to the UK average, with a first-time pass rate of just 74.5% against the national 80%. The good news is that dangerous defects are essentially non-existent in this cohort, and the diesel engine itself isn't the weak link—it passes at 74.4%, suggesting the problems lie elsewhere in the car's systems.
At nearly 100,000 miles median, these cars are getting worked hard, and that shows up in the failure numbers: expect an average of 0.59 failures per test, which points to cumulative wear on suspension, brakes, and emissions components rather than one specific design flaw. Before buying, budget for pre-purchase inspection by a diesel specialist and factor in a higher-than-average MOT failure rate over the next couple of years.
What to check before buying a 2013 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.
