2019 Audi A6 Sport 40 TDI S A
CarHunch analysed 156 real MOT records for the 2019 Audi A6 Sport 40 TDI S A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2019 Audi A6 is a strong performer—a first-time pass rate of 91.9% sits well clear of the UK average of 80%, and crucially, none of the 156 diesel examples analysed have ever shown a dangerous defect. The diesel engine is proving reliable in this model, with an average of just 0.15 failures per vehicle and effectively zero advisories on record.
At a median mileage of 61,732 miles for a five-year-old car, these A6s are running close to expected use, which supports the excellent pass rate. The combination of minimal failures, no dangerous defects, and strong MOT performance suggests the 40 TDI is a dependable choice—but when shopping, check the full service history to confirm the diesel engine has had regular maintenance, as that's what's keeping these failure rates this low.
What to check before buying a 2019 Audi A6 Sport 40 TDI S 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.
