2021 Mercedes Benz Sprinter 317 Progressive CDI

CarHunch analysed 478 real MOT records for the 2021 Mercedes Benz Sprinter 317 Progressive CDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This Sprinter 317 is a reliably robust commercial vehicle, with an 82.3% first-time pass rate that sits comfortably above the UK average of 80%, and only 15.7% of these vans have ever recorded a dangerous defect—a manageable risk profile for a used buyer. The diesel engine is clearly the expected choice here, and these figures suggest it's holding up well in service.

At nearly 91,000 km average mileage for a three-year-old van, these are working vehicles being properly used, which actually validates the pass rate as genuine rather than garage-queen inflated. The modest 0.57 failures per test and 2.2 advisories per vehicle indicate routine maintenance issues rather than systemic problems, so budget for regular servicing and check the service history carefully when you view one—this van's survival depends on it being looked after properly.

What to check before buying a 2021 Mercedes Benz Sprinter 317 Progressive CDI

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.
