188 real MOT outcomes analysed • 65.4% first-time pass rate

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.
