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

The vehicle is currently roadworthy, but the maintenance trend indicates a reactive rather than proactive approach. The most recent test on 14 May 2026 at 70,400 miles resulted in a failure due to poor parking brake efficiency and pitted front brake discs. While the vehicle passed immediately after these remedial works, the recurring nature of the braking issues—which also appeared in 2024—suggests that components are only addressed when they reach legal limits rather than being serviced at standard intervals. The Sprinter has covered 70,400 miles over five years, averaging approximately 14,000 miles per annum. This mileage is consistent with active commercial use but places significant demand on the heavy-duty suspension and braking systems. Between September 2024 and May 2026, the vehicle clocked 23,593 miles in just 20 months. This high rate of accumulation explains the accelerated wear seen on consumables, such as the thin nearside front brake pads and low tread depth issues recorded during the September 2024 failure. A buyer must conduct a thorough physical inspection of the parking brake mechanism, as it has failed efficiency requirements in two separate tests. The pitting and scoring on the front brake discs noted in 2026 indicate either prolonged exposure or excessive heat, which can lead to judder. Furthermore, the offside front tyre showing inner-edge wear recorded in 2024 points toward a potential alignment issue or worn suspension bushes that should be verified to prevent premature tyre replacement.
