Should I check the MOT history before buying a 2021 Mercedes Benz Sprinter 315 Premium CDI?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

Based on MOT data from 673 vehicles, the 2021 Mercedes Benz Sprinter 315 Premium CDI has a first-time MOT pass rate of 86.5%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 Mercedes Benz Sprinter 315 Premium CDI?

The 2021 Mercedes-Benz Sprinter 315 Premium CDI is a reliable workhorse, passing its MOT on first attempt 85.2% of the time—a solid 5.2 percentage points above the UK average—with only 10% ever recording a dangerous defect. This diesel van shows genuine durability in the test bay, avoiding the structural weak points that plague less robust commercial vehicles.

At nearly 66,000 miles on average, these vans are racking up typical business mileage for their age, and the 0.43 failures per vehicle suggest most problems are catching issues rather than systemic failures. Focus your pre-purchase inspection on the 2.1 advisories per vehicle (usually wear items like brakes and suspension bushes on a van this well-used), and always verify full service history to confirm that the manufacturer's maintenance schedule has been kept.

The 2021 Mercedes Benz Sprinter 315 Premium CDI passes its MOT first time more often than most UK vehicles (86.5% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

✅ Good baseline reliability. A 86.5% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 2.1 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 673 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
