Seat Leon Stylance TDI (2006)
2006 Seat Leon Stylance TDI
CarHunch analysed 422 real MOT records for the 2006 Seat Leon Stylance TDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2006 SEAT Leon TDI diesel struggles at MOT time, with a first-time pass rate of just 71.9%—nearly 9 points below the UK average of 80%—though the complete absence of dangerous defects (0%) at least means failures tend to be fixable rather than safety-critical. Averaging over 151,000 miles and carrying 1.04 failures per vehicle, these cars are showing their age and demanding attention to get through the test.
The median mileage of 149,810 suggests these are genuinely well-used examples, so expect wear-related costs when you buy. Before purchasing, have a pre-purchase inspection focus on common diesel TDI failure areas like the fuel system, turbo, and exhaust after-treatment kit, and budget for remedial work—the MOT pass rate hints that surprises are likely.
What to check before buying a 2006 Seat Leon Stylance TDI
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.
