2021 Mercedes-Benz Sprinter 315 Premium CDI 1.9L Diesel · KN71 XCB

The Sprinter currently holds a valid MOT, having passed on 13 March 2026 at 71,628 miles with zero defects recorded. That clean bill of health followed a failure just three days earlier on 10 March 2026 at 71,626 miles, where the parking brake efficiency fell below minimum requirements. The fact the retest passed within 72 hours suggests the issue was addressed promptly, but the failure itself is notable on a vehicle presenting as well-maintained. The overall trend is broadly stable, though the recent parking brake fault introduces a minor question mark around the consistency of braking system upkeep. At roughly five years old with 71,628 miles recorded, this Sprinter has covered approximately 14,300 miles per year, placing it firmly in the high-mileage bracket for its age. The record shows a significant gap between the August 2024 test at 49,148 miles and the August 2025 test at 68,916 miles, representing nearly 20,000 miles added in a single 12-month interval. That spike indicates sustained heavy use, likely commercial or long-distance work, which accelerates wear on consumables, suspension components, and drivetrain parts. The mileage progression is otherwise consistent with no obvious anomalies suggesting tampering or extended periods of disuse. The recurring advisories deserve attention. Both the August 2025 test flagged lipped front and rear brake discs with pads measuring 6mm, while the March 2025 test also noted a deteriorated rear registration plate. The disc wear recorded in August 2025 was described as not excessive, yet the subsequent parking brake failure in March 2026 raises the possibility that braking components have not been replaced or serviced on a disciplined schedule. A buyer should inspect the current condition of all brake discs, pads, and the parking brake mechanism, including cables and adjusters, for uneven wear, corrosion, or binding. The handbrake fault specifically warrants a physical test on an incline to confirm it holds securely under load. Beyond the braking system, the high annual mileage and commercial nature of this vehicle mean suspension bushes, coil springs, shock absorbers, and steering components are likely approaching the stage where deterioration becomes visible. The clean March 2026 test is reassuring, but MOTs only capture a snapshot. A prospective buyer should arrange an independent inspection focusing on structural integrity around the load area, subframe mounting points, and any signs of corrosion or fatigue consistent with a working van covering 14,000 miles annually. The registration plate deterioration, while minor, also hints that basic cosmetic upkeep may have been deprioritised in favour of keeping the vehicle on the road.
