2007 Audi A4 S Line TDI 140

CarHunch analysed 405 real MOT records for the 2007 Audi A4 S Line TDI 140. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2007 A4 S Line TDI 140 is a notably unreliable prospect, with a first-time MOT pass rate of just 60.7%—nearly 20 percentage points below the UK average of 80%. The good news is that dangerous defects are absent from this cohort, so safety-critical failures aren't the issue here.

At 146,194 miles median, these cars have covered typical distance for their age, yet they're still averaging 1.14 failures per test, suggesting wear and maintenance issues rather than exceptional mileage abuse. If you're considering one, budget for repair costs and have a pre-purchase inspection by a diesel specialist focus on the fuel injection and turbo systems, where TDI engines often develop expensive problems.

What to check before buying a 2007 Audi A4 S Line TDI 140

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.
