Peugeot 308 (2018)
2018 Peugeot 308
CarHunch analysed 8,972 real MOT records for the 2018 Peugeot 308. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2018 Peugeot 308 passes its MOT slightly above the UK average at 82.7%, but nearly 30% of vehicles in this cohort have recorded a dangerous defect at some point—a notably high proportion that warrants caution. Petrol versions are meaningfully more reliable than diesels, with pass rates of 84.8% versus 80.0% respectively, suggesting the petrol engine is the safer choice if you have the option.
At a median mileage of just under 37,000 miles for a six-year-old car, these vehicles are running relatively light, which partly explains the decent pass rate. The average car racks up 0.91 failures and 6.0 advisories per test, pointing to recurring minor issues rather than catastrophic problems—typically suspension and lighting work. Have any potential purchase independently inspected and specifically ask the seller about its MOT history, particularly whether it's ever had advisories for steering or brake components.
Petrol vs Diesel
Pass rate difference of 4.8 percentage points — worth knowing if you're choosing between the two.
What to check before buying a 2018 Peugeot 308
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.
- ⚠️ 29.7% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
