Audi A6 (2016)
2016 Audi A6
CarHunch analysed 15,901 real MOT records for the 2016 Audi A6. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2016 Audi A6 passes its MOT on first attempt 85.1% of the time, comfortably ahead of the UK average of 80%, but nearly 27% of these cars have recorded a dangerous defect at some point — a significant concern for buyers. Petrol versions perform better at 88.7% pass rate compared to diesel at 84.9%, suggesting the petrol engines are inherently more robust, though the diesel dominates the used market with 95% of the cohort.
At a median 63,331 miles for an eight-year-old car, these A6s have covered reasonable mileage for their age, and the low failure rate of 0.82 per vehicle indicates most mechanical issues are caught early. However, the high advisory count of 5.9 per car points to persistent minor wear — suspension and brake components particularly — so budget for proactive maintenance items when you inspect one, and specifically have a pre-purchase inspection focus on suspension geometry and brake pad thickness.
What to check before buying a 2016 Audi A6
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.
- ⚠️ 26.8% 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.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
