2021 Mercedes-Benz Sprinter 315 Progressive CDI 1.9L Diesel · KP21 DPX

The vehicle is currently roadworthy following a pass on March 17, 2026, but the recent test history reveals a sudden decline in maintenance standards compared to previous years. While the vehicle achieved two clean passes in a row previously, the most recent MOT failure at 70,901 miles identified multiple critical safety and lighting defects. The presence of a binding nearside rear service brake and insufficient parking brake efficiency suggests that the braking system had been neglected or required significant attention prior to the March 2026 inspection. The mileage pattern indicates a consistent high-use profile, averaging approximately 14,000 miles per year. Between March 2024 and March 2025, the vehicle covered 18,420 miles, followed by another 16,697 miles in the subsequent year leading up to the latest test. This rapid accumulation suggests the Sprinter is used for heavy commercial duties, which accelerates the wear on suspension components, drivetrain elements, and consumables. The intervals between the tests are regular, but the high mileage places significant strain on mechanical components between annual intervals. A buyer must conduct a thorough inspection of the braking system to ensure the issues flagged in March 2026 were fully rectified. The tester noted a binding rear caliper and poor parking brake performance, which often necessitates a check for seized pistons, worn brake shoes, or stretched adjustment cables. The failure of the nearside headlamp aim and the offside repeater indicates a lack of basic pre-test checks by the owner. Given the high mileage, the buyer should also inspect the suspension bushes and coil springs for signs of premature wear or fatigue that frequently follow heavy-duty usage.
