Mercedes Benz E220 SE CDI Auto (2014)
2014 Mercedes Benz E220 SE CDI Auto
CarHunch analysed 686 real MOT records for the 2014 Mercedes Benz E220 SE CDI Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2014 Mercedes-Benz E220 SE CDI is a significant reliability concern: only 28.9% pass their MOT first time, compared to the UK average of 80%. At nearly 87,000 miles median mileage, these cars are still accumulating failures at 0.26 per vehicle—well above what you'd expect from a six-to-ten-year-old executive saloon, though the zero dangerous defect rate offers some reassurance.
The consistent diesel performance (28.4% pass rate) shows the problem isn't fuel-specific but fundamental to the model's engineering or age-related wear. Before buying one, get a pre-purchase inspection focused on the electrical and emissions systems where older Mercedes typically fail, and factor in repeated MOT visits and repairs as a realistic ownership cost.
What to check before buying a 2014 Mercedes Benz E220 SE CDI Auto
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.
