2021 Mercedes Benz Sprinter 516 CDI Auto

CarHunch analysed 119 real MOT records for the 2021 Mercedes Benz Sprinter 516 CDI Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2021 Sprinter 516 CDI is failing its MOT at an alarming rate: only 18.2% pass first time, compared to the UK average of 80%. While dangerous defects haven't appeared in this cohort yet, the sheer scale of initial failures is a serious red flag for any prospective buyer.

At a median of 31,234 miles for a three-year-old van, these vehicles are running relatively light, which makes the failure rate even more concerning—age and mileage aren't excuses here. Before committing to one of these, get a full pre-purchase inspection focused on the specific components that typically fail on this model, as the MOT data suggests systemic issues rather than random faults.

What to check before buying a 2021 Mercedes Benz Sprinter 516 CDI 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.
