Peugeot 407 SE HDI (2008)
2008 Peugeot 407 SE HDI
CarHunch analysed 120 real MOT records for the 2008 Peugeot 407 SE HDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2008 Peugeot 407 SE HDi is a serious reliability concern, with a first-time MOT pass rate of just 43.5%—well below the UK average of 80%—meaning more than half fail on their first attempt. The good news is that dangerous defects are absent from this cohort, so safety-critical failures aren't the issue here.
At 120,000 miles on average, these cars are showing their age, and the 0.58 failures per vehicle suggest persistent mechanical niggles rather than catastrophic problems. If you're considering one, budget for remedial work before or shortly after purchase, and factor in an extended pre-purchase inspection focusing on the diesel engine and running gear, as the failure pattern indicates wear-related issues rather than design defects.
What to check before buying a 2008 Peugeot 407 SE HDI
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.
