2017 Audi A1 S Line TFSI

CarHunch analysed 114 real MOT records for the 2017 Audi A1 S Line TFSI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2017 A1 S Line TFSI is a weaker performer than average, with a first-time MOT pass rate of just 63.1% against the UK average of 80%, suggesting you should budget for repairs or retesting on your first visit to the test station. The good news is that dangerous defects are absent from this cohort and average failures are minimal at 0.12 per vehicle, so issues tend to be minor rather than safety-critical.

At a median mileage of 45,556 miles for a seven-year-old car, these vehicles are running below typical for age, which partly explains why failures aren't severe—they simply haven't accumulated the wear. Before buying, factor in a pre-purchase inspection to catch the small maintenance items that seem to be holding back pass rates, then expect straightforward ownership if those are addressed.

What to check before buying a 2017 Audi A1 S Line TFSI

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.
