2020 Mercedes-Benz Sprinter 315 Progressive CDI 1.9L Diesel · KS70 BKD

A critical failure of the braking system marks the most recent testing cycle, contrasting with a previously clean record. On 2025-11-24, the vehicle failed on dangerous defects regarding the offside rear brake pads and discs before passing later that day. This indicates a recent period of significant wear on the rear braking assembly and lighting malfunctions, diverging from the defect-free passes recorded in 2023 and 2024. The recorded mileage of 88,133 miles represents a high annual accumulation rate of approximately 14,689 miles per year. This usage profile suggests the vehicle has been operated heavily, which typically accelerates the wear of drivetrain components, suspension bushings, and braking consumables. Such high-intensity usage increases the likelihood of fatigue in heavy-duty components common to commercial vehicles of this specification. Given the dangerous failure of the offside rear brake disc and pads, a thorough inspection of the current braking hardware is essential to ensure the replacements are of a suitable standard. During a test drive, the driver should be alert for any pedal judder or uneven braking force, which could indicate issues with the caliper or the quality of the newly fitted discs. The current advisory regarding the nearside front tyre being worn close to the legal limit requires immediate verification of the remaining tread depth and an assessment of the tyre's edge wear to determine if there is an underlying wheel alignment issue. Attention should also be paid to the electrical system following the failures of the offside rear stop and position lamps to confirm that all multi-source lighting elements are fully operational. While the earlier records were clean, the combination of high mileage and recent brake failure necessitates a close examination of the suspension for any play in the linkages or signs of bushing degradation, which often manifests as knocks or vibrations when traversing uneven road surfaces.
