Audi A5 (2017)
2017 Audi A5
CarHunch analysed 15,176 real MOT records for the 2017 Audi A5. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2017 Audi A5 passes its MOT on the first attempt 89.2% of the time, well above the UK average of 80%, but there's a significant caveat: 27% of these cars have recorded a dangerous defect at some point, which is substantially higher than typical and should concern any potential buyer. Petrol versions perform marginally better (90% pass rate) than diesels (88.6%), though the difference is small.
At a median mileage of 53,779 miles for a seven-year-old car, these A5s are running slightly below average wear, yet they still accumulate 6.2 advisories per vehicle on average, suggesting routine maintenance costs will be noticeable. Before buying, run a full service history check and have a pre-purchase inspection focus on the areas flagged most often in advisories—likely suspension, braking, and electrical components—as these recurring issues point to where money will need to go.
What to check before buying a 2017 Audi A5
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.
- ⚠️ 27% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
