Audi A7 S Line Black Ed TDI Quat SA (2015)
2015 Audi A7 S Line Black Ed TDI Quat SA
CarHunch analysed 129 real MOT records for the 2015 Audi A7 S Line Black Ed TDI Quat SA. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2015 Audi A7 S Line Black Edition is a reliability concern: only 55.6% pass their MOT first time, well below the UK average of 80%, and the diesel engines show no improvement at 55.5%. The good news is that dangerous defects are absent from this cohort, so failures tend to be fixable rather than safety-critical.
At 74,245 miles median, these cars are showing their age predictably, but the low average of 0.27 failures per vehicle suggests problems are manageable rather than catastrophic when they do arise. Before buying, get a pre-purchase inspection focused on the diesel engine and emissions systems—nearly half of these cars will need work to pass their next test.
What to check before buying a 2015 Audi A7 S Line Black Ed TDI Quat SA
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.
