Audi Q7 Sport 45 TDI MHEV Quattro A (2020)
2020 Audi Q7 Sport 45 TDI MHEV Quattro A
CarHunch analysed 160 real MOT records for the 2020 Audi Q7 Sport 45 TDI MHEV Quattro A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This Q7 diesel is performing above the UK average, with an 86% first-time pass rate compared to 80% nationally, and only 8.8% of vehicles ever flagged with a dangerous defect—a reassuring figure for a large SUV. The reliability picture is solid without being exceptional.
At 36,811 miles median, these 2020 models sit right where you'd expect for their age, suggesting typical use patterns rather than abuse. With just 0.24 failures per vehicle but 2.3 advisories on average, expect minor wear items and scheduled maintenance to dominate future MOTs rather than serious failures—budget for routine upkeep and have a pre-purchase inspection focus on suspension and brake components, which typically rack up the advisory flags on larger diesels.
What to check before buying a 2020 Audi Q7 Sport 45 TDI MHEV Quattro A
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.
