Peugeot 407 SE HDI (2004)
2004 Peugeot 407 SE HDI
CarHunch analysed 112 real MOT records for the 2004 Peugeot 407 SE HDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2004 Peugeot 407 SE HDi is a serious reliability concern, passing its MOT just 32.1% of the time against the UK average of 80%—nearly two-and-a-half times worse. The diesel variant, which accounts for 110 of the 112 cars analysed, shows a 31.1% pass rate, indicating this isn't a fuel-type issue but a fundamental problem with the model itself.
At nearly 175,000 miles on average, these cars are well-used, yet they're still racking up 0.33 failures per vehicle on test, suggesting age-related wear is compounding pre-existing weaknesses rather than explaining them away. If you're considering one, budget for significant repairs before or shortly after purchase, and get a full pre-buy inspection from a diesel specialist who knows the 407's common fault patterns.
What to check before buying a 2004 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.
