2017 Audi Q7 S Line TDI Quattro Auto
CarHunch analysed 566 real MOT records for the 2017 Audi Q7 S Line TDI Quattro Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2017 Audi Q7 S Line TDI Quattro Auto has a first-time MOT pass rate of 60.5%, which is notably below the UK average of 80%, indicating this diesel model struggles more often on its initial test. The good news is that dangerous defects are absent from this cohort—no vehicles recorded any serious safety issues—so failures tend to be minor or advisory matters rather than hazards.
At a median mileage of 75,640 miles for a seven-year-old vehicle, these Q7s are running close to expected wear levels, yet they're averaging 0.24 failures per car, suggesting minor niggles accumulate across the fleet. The complete absence of advisories combined with the low failure count tells you these aren't complex breakdown machines, but rather that small, fixable items are tripping up nearly 40% of first-time testers; have a pre-purchase inspection focus on diesel particulate filter condition and emissions systems, which typically drive failures on this platform.
What to check before buying a 2017 Audi Q7 S Line TDI Quattro Auto
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.
