Renault Megane Sl Oasis DCI 85 E4 (2005)
2005 Renault Megane Sl Oasis DCI 85 E4
CarHunch analysed 117 real MOT records for the 2005 Renault Megane Sl Oasis DCI 85 E4. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2005 Renault Megane diesel is significantly less reliable than the UK average, with a first-time pass rate of just 64.5% against the national benchmark of 80%—meaning one in three examples will need repairs before passing MOT. The good news is that dangerous defects are absent from this cohort, so structural and safety failures aren't a pattern concern.
At nearly 121,000 miles, these cars have racked up typical mileage for their age, and they're averaging 0.91 failures per test, which suggests age-related wear rather than fundamental design flaws. If you're considering one, budget for remedial work on electrics or emissions systems (common diesel weak points), and factor in a pre-purchase inspection to identify any outstanding failures before you commit.
What to check before buying a 2005 Renault Megane Sl Oasis DCI 85 E4
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.
