Mercedes E220 CDI Avantgarde Auto (2006)
2006 Mercedes E220 CDI Avantgarde Auto
CarHunch analysed 123 real MOT records for the 2006 Mercedes E220 CDI Avantgarde Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This E220 CDI is a reliability red flag: only 13.7% pass their MOT first time, versus the UK average of 80%, and buyers should expect nearly one failure per vehicle (0.42 average) when they take one to test. The good news is that dangerous defects are absent from this cohort, so the failures tend to be fixable rather than safety-critical.
At nearly 141,500 miles median, these are high-mileage cars, and the complete absence of recorded advisories suggests inspectors are finding outright failures rather than emerging issues—a sign that maintenance may have been deferred until things break entirely. Before purchasing, budget for immediate repairs and insist on a full pre-purchase inspection, because the MOT pattern shows these cars need work done sooner rather than later.
What to check before buying a 2006 Mercedes E220 CDI Avantgarde 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.
