2022 Mercedes-Benz Sprinter 315 Progressive CDI 1.9L Diesel · WR22 AAV

Recent testing reveals a shift toward emerging wear on critical braking and suspension components, following a clean record in May 2025. A failure on 25 February 2026 due to insufficient parking brake efficiency was rectified to achieve a pass on the same day, though the vehicle now carries advisories for front brake disc wear and play in the offside front lower suspension arm ball joint. This indicates a trend of increasing mechanical wear as the vehicle ages. The recorded mileage of 70,206 miles over approximately four years represents a high annual accumulation rate of roughly 17,552 miles. This level of usage typically accelerates the wear of high-stress consumables, suspension linkages, and drivetrain components compared to lower-mileage examples. The transition from a defect-free test in 2025 to multiple advisories in early 2026 is consistent with this high-utilization profile. Attention should be directed toward the front-end suspension and braking system during a physical inspection. The reported play in the offside front lower suspension arm ball joint may manifest as a knocking or clicking sound when traversing uneven road surfaces or during low-speed steering maneuvers. Given the advisory regarding worn front brake discs and the recent failure of the parking brake efficiency, the braking system requires close scrutiny. During a test drive, the parking brake should be tested on a gradient to ensure it holds the vehicle securely without slipping. The service brake pedal should be monitored for any judder or pulsation, which can be indicative of the disc wear noted in the February 2026 test. Finally, the windscreen should be inspected for the recorded damage to ensure it does not obstruct the driver's field of vision or risk further cracking.
