2021 Mercedes Benz Sprinter 314 Premium CDI
CarHunch analysed 709 real MOT records for the 2021 Mercedes Benz Sprinter 314 Premium CDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2021 Mercedes-Benz Sprinter 314 Premium CDI has a first-time pass rate of 77.5%, slightly below the UK average of 80%, and 14.8% of vehicles have recorded a dangerous defect at some point—a moderately concerning figure for a commercial workhorse. This suggests reliability is reasonable but not outstanding, and buyers should factor in the elevated risk of serious faults.
At a median mileage of 56,500 miles for a three-year-old van, these Sprinters are running relatively hard, yet they're averaging only 0.68 failures per MOT and 2.5 advisories—fairly typical wear-and-tear for a commercial vehicle under load. Before buying, have a pre-purchase inspection focus on the cooling system, electrical harnesses, and transmission mounts, as these commonly accumulate issues on high-mileage examples.
What to check before buying a 2021 Mercedes Benz Sprinter 314 Premium 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.
