This 2008 Peugeot 308 diesel has a serious reliability problem: only 50.5% pass their MOT first time, nearly 30 points below the UK average of 80%. The good news is that dangerous defects are essentially non-existent at 0%, so while these cars fail frequently, they're not failing on safety-critical items.

At 127,861 miles median, these diesels have covered typical mileage for their age, yet they're averaging 0.86 failures per test—suggesting wear and maintenance issues beyond just high mileage. Before buying one, get a pre-purchase inspection focused on suspension, emissions, and cooling systems, which are the most common failure categories for this model.

What to check before buying a 2008 Peugeot 308 S Dt

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.
