Audi S5 Edition 1 TDI MHEV Quat A (2020)
2020 Audi S5 Edition 1 TDI MHEV Quat A
CarHunch analysed 129 real MOT records for the 2020 Audi S5 Edition 1 TDI MHEV Quat A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2020 Audi S5 diesel edges past the UK average with an 83.3% first-time pass rate, suggesting solid baseline reliability—though 17.1% of these vehicles have experienced a dangerous defect at some point, which is worth factoring into your inspection checklist. The relatively low 0.43 average failures per vehicle is encouraging, but the 2.4 advisories suggest minor wear items are cropping up regularly.
At 36,000 miles median, these cars are running slightly below the typical mileage for their age, which should mean less accumulated stress on mechanical systems. Before purchase, budget for those recurring small fixes and get a pre-buy inspection that specifically checks suspension, brakes, and emissions equipment—the areas where this model tends to generate advisories.
What to check before buying a 2020 Audi S5 Edition 1 TDI MHEV Quat 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.
