1998 Mercedes Benz 412 D

CarHunch analysed 210 real MOT records for the 1998 Mercedes Benz 412 D. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1998 Mercedes-Benz 412 D passes its MOT first time just 71% of the time, nine points below the UK average of 80%, and nearly 29% of examples have recorded dangerous defects—a serious concern for a buyer. The combination of a weak pass rate and high dangerous defect prevalence suggests this model demands scrupulous pre-purchase inspection and robust maintenance discipline.

At an average mileage of 229,000 km, these vans are heavily used workhorses, and the data bears that out: they rack up nearly 2.7 failures per test and 14.5 advisories, indicating wear-related issues are endemic. Before committing to one, have an independent Mercedes-Benz specialist conduct a pre-purchase inspection focusing on brake systems, suspension, and engine seals—the 412 D's weak spot areas.

What to check before buying a 1998 Mercedes Benz 412 D

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.
  • ⚠️ 28.6% 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.
