2014 Mercedes Benz E300 Amg Sport Bluetec Hybrida

CarHunch analysed 380 real MOT records for the 2014 Mercedes Benz E300 Amg Sport Bluetec Hybrida. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

**This E300 hybrid is in serious trouble on the MOT test.** With a first-time pass rate of just 3% against the UK average of 80%, these cars are failing systematically—and the diesel-electric variant shows a 0% pass rate across 368 vehicles tested, suggesting a fundamental issue with how this powertrain performs under MOT conditions.

At an average mileage of 93,966 miles, these are relatively high-mileage examples, and the hybrid complexity combined with the near-total failure pattern points to recurring issues that aren't being caught by the advisory system. If you're considering this model, you need a pre-purchase inspection from a Mercedes specialist familiar with hybrid systems, because the factory data here indicates the hybrid components are systematically problematic at this age.

What to check before buying a 2014 Mercedes Benz E300 Amg Sport Bluetec Hybrida

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.
