2004 Ford Mondeo Mistral Tdci

CarHunch analysed 118 real MOT records for the 2004 Ford Mondeo Mistral Tdci. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2004 Ford Mondeo Mistral TDCi is a genuinely problematic used buy: only 56.7% pass their MOT first time, well below the UK average of 80%, which means more than four in ten will need repairs before they're legal to drive. The good news is that dangerous defects are rare (0%), so you're not looking at safety-critical failures, but the diesel engine's track record shows these cars simply wear harder than most.

At 142,659 miles on average, these Mondeos have genuinely high mileage for their age, which explains why owners are averaging 0.66 failures per test. If you're considering one, budget for repairs immediately and have a pre-purchase inspection by a diesel specialist, because age plus mileage on these engines creates a high likelihood of needing work within months of purchase.

What to check before buying a 2004 Ford Mondeo Mistral Tdci

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.
