Mercedes Benz Sprinter 516 CDI (2021)
2021 Mercedes Benz Sprinter 516 CDI
CarHunch analysed 258 real MOT records for the 2021 Mercedes Benz Sprinter 516 CDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Mercedes-Benz Sprinter 516 CDI has a first-time MOT pass rate of just 22.6%, significantly below the UK average of 80%, making it a serious reliability concern for buyers. With zero dangerous defects recorded across the 258 vehicles analysed, the failures appear to be technical rather than safety-critical, but the sheer volume of problems is striking.
At 42,946 miles on average, these vans are relatively low-mileage for their age, yet they're already failing MOTs at an alarming rate—suggesting design or manufacturing issues rather than wear-and-tear. If you're considering this model, have a pre-purchase inspection by a Mercedes commercial specialist, as routine servicing alone clearly isn't preventing these failures.
What to check before buying a 2021 Mercedes Benz Sprinter 516 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.
