Audi Sq5 TDI Quattro Auto (2015)
2015 Audi Sq5 TDI Quattro Auto
CarHunch analysed 188 real MOT records for the 2015 Audi Sq5 TDI Quattro Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2015 Audi SQ5 TDI Quattro Auto is a reliability concern: its first-time MOT pass rate sits at 65.4%, well below the UK average of 80%, and nearly one in three vehicles fail their test. No dangerous defects have been recorded across the 188 vehicles analysed, which is a positive, though the gap to the national average is substantial and suggests systemic issues with this model.
At 84,500 miles median mileage, these cars have covered a typical distance for their age, yet the failure rate isn't explained by high running. The low failure count (0.16 per vehicle) and zero advisories point to a pattern where vehicles either pass cleanly or fail outright—likely pointing to specific component weaknesses rather than general wear. If you're considering one, budget for a thorough pre-purchase inspection by a diesel specialist and factor in higher-than-average maintenance risk.
What to check before buying a 2015 Audi Sq5 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.
