The 2021 Audi Q4 e-tron S Line 40 passes its MOT on the first attempt 90.8% of the time, well above the UK average of 80%, which suggests strong build quality and reliability for this relatively young electric SUV. Only 11.2% of vehicles in this cohort have ever recorded a dangerous defect, putting it in a reassuringly safe bracket for buyers.
At 35,041 miles average and 32,360 miles median, these cars are running slightly higher than typical for their age, yet they average just 0.24 failures per vehicle—indicating that even with decent mileage, they're holding up well. The 1.6 advisories per car suggest minor wear items are cropping up, so budget for brake fluid and suspension checks as preventative maintenance when buying used, rather than expecting serious repairs.
What to check before buying a 2021 Audi Q4 E Tron S Line 40
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.
