Audi A6 SE TDI Ultra S A (2014)
2014 Audi A6 SE TDI Ultra S A
CarHunch analysed 116 real MOT records for the 2014 Audi A6 SE TDI Ultra S A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2014 A6 TDI Ultra is a serious reliability concern: only 39.4% pass first time against the UK average of 80%, and with zero dangerous defects recorded, the failures are spread across routine wear items rather than safety-critical systems. The median CarHunch score of 30 out of 100 reflects consistent mechanical issues across the cohort.
These cars are averaging 96,341 miles at test—high for a 2014—and while advisories are mercifully absent, the 0.25 average failures per vehicle suggests ongoing costs are inevitable. Before buying, budget for repairs and insist on a full service history; the pass rate gap this wide is a warning sign you'll need hands-on ownership experience or a trusted mechanic.
What to check before buying a 2014 Audi A6 SE TDI Ultra 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.
