2021 Mercedes-Benz Sprinter 314 Progressive CDI 2.1L Diesel · NA70 AAZ

The most recent DVSA MOT test dated 27 January 2026 resulted in a PASS, although it is important to note that the same date also records a FAIL with a major defect for the nearside windscreen wiper not clearing the windscreen effectively. This suggests the failure was rectified shortly afterwards, likely by replacement of the wiper blade or wiper arm mechanism, allowing the vehicle to pass on the same day. The preceding test on 30 January 2025 was passed with a minor defect recorded for a defective front windscreen wiper blade, indicating an ongoing concern with wiper performance over consecutive tests. The earlier test on 23 January 2024 was passed cleanly with only advisories relating to fitted engine covers restricting component visibility and a nail in the nearside rear tyre. The maintenance trend is broadly stable, but the recurring wiper-related defects warrant attention as they may indicate a deeper issue with the wiper linkage, motor, or electrical supply rather than merely blade wear. With a recorded mileage of 7,934 miles over approximately five years, this Mercedes-Benz Sprinter is operating at an exceptionally low annual usage rate of around 1,587 miles per year. For a commercial vehicle of this class, such low mileage is unusually low and strongly suggests prolonged periods of standing or storage rather than active service. While low mileage generally preserves mechanical components such as the engine, transmission, and drivetrain, it introduces specific risks associated with inactivity. Brake discs and callipers can suffer from corrosion and seizure due to lack of regular use, leading to uneven braking or binding. Diesel fuel systems can be affected by water ingress or stale fuel, and oil seals may develop minor leaks after long idle periods. Given the very low usage profile, prospective buyers should undertake a thorough physical inspection beyond the MOT record. The tyres should be examined carefully for sidewall perishing and cracking, as rubber compounds degrade with age regardless of tread depth, and a tyre older than five years warrants replacement regardless of remaining tread. The braking system should be inspected for surface corrosion on the discs and any signs of seized calliper slides or handbrake mechanism binding. The 12-volt battery should be load tested, as prolonged standing without regular charging cycles drastically shortens battery life. Diesel particulate filter condition should be considered, as short infrequent journeys prevent the regeneration cycle from completing, which can lead to blockages and warning lights. All fluids including engine oil, coolant, brake fluid, and power steering fluid should be checked for condition and service intervals, as these degrade with calendar age. During a test drive, particular attention should be paid to any clunks or knocking from the suspension, which may indicate perished bushes or corroded coil springs from standing. The brakes should be tested for smooth operation and the handbrake for confident holding, as sticking callipers are common on low-use vehicles. Listen for any hesitation, misfires, or excessive smoke from the diesel engine, which could suggest DPF or fuel system issues linked to short journeys. Verify that the wiper system operates correctly across all speeds and that the blades clear the screen fully, resolving the historical MOT advisory. Finally, confirm a full service history with documented timing belt or chain inspection intervals, as calendar-based servicing is critical for vehicles of low annual mileage.
