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

A history of critical braking failures and structural modifications defines the mechanical record of this vehicle. While the test on 17 December 2025 resulted in a pass, the record is marked by a dangerous failure in December 2024 involving parking brake efficiency below 50 percent and insufficient service brake efficiency. The current status includes an advisory regarding modified rear leaf springs that are hitting the floor, indicating a deviation from factory specifications. The recorded mileage of 70,670 miles represents an average annual accumulation of approximately 11,778 miles, which is typical for a vehicle of this age and type. This usage pattern suggests a consistent application of the drivetrain and chassis components, meaning wear on consumables such as brake pads, discs, and suspension bushings is likely to be commensurate with standard operational cycles for a light commercial vehicle. Given the previous dangerous failure of the parking brake and the major deficiency in service brake efficiency, a rigorous evaluation of the braking system is essential. During a test drive, the buyer should check for any pedal judder, a spongy feel under heavy braking, or any pull to one side, which could indicate uneven caliper pressure or remaining issues with the hydraulic system. The parking brake must be tested on a gradient to ensure it holds the vehicle securely without slipping. The advisory regarding modified rear leaf springs requires specific attention to the vehicle's rear suspension geometry and load-carrying capacity. The buyer should inspect the rear arches and chassis for signs of rubbing or impact damage where the springs are reported to be hitting the floor. Listen for knocks or metallic clunks when driving over speed bumps or uneven surfaces, as modified suspension can alter the damping characteristics and increase the risk of premature wear on other suspension linkages.
