2009 Mercedes Benz E

CarHunch analysed 11,472 real MOT records for the 2009 Mercedes Benz E. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2009 Mercedes-Benz E passes its MOT slightly above the UK average at 82.8%, which is reassuring—but the elephant in the room is that 40.9% of these cars have recorded a dangerous defect at some point, well above acceptable levels and a serious buyer concern. Petrol models fare better at 86.6% pass rate versus diesel at 82.5%, suggesting the petrol variant is marginally more robust, though the sample is much smaller.

At around 85,500 miles median, these cars have covered typical mileage for their age, yet they're averaging 2.68 failures and 17.5 advisories per test, pointing to aging components and wear that's becoming expensive to manage. Before buying, run a full pre-purchase inspection focused on suspension, electrics, and brake systems—this generation is prone to costly failures in those areas, and the high dangerous defect rate means skipping due diligence is a false economy.

What to check before buying a 2009 Mercedes Benz E

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.
  • ⚠️ 40.9% 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.
