2021 Mercedes-Benz Sprinter 315 Progressive CDI 1.9L Diesel · KS21 WKB

The vehicle passed its most recent MOT on 2025-08-06 at 115,305 miles, but this follows a significant failure just five days earlier where the tester flagged multiple critical defects including an inoperative engine management warning light and a faulty supplementary restraint system (airbag) warning lamp. These serious electrical system faults, alongside failed lighting components, indicate a period of poor maintenance or neglect that was only addressed immediately before the retest. The overall trend is therefore concerning, suggesting reactive rather than proactive care, with the vehicle failing on fundamental safety systems. The recorded mileage of 115,305 miles on a 2021-registered vehicle equates to an average of approximately 23,061 miles per year, which is high for a five-year-old commercial vehicle and suggests sustained heavy use. This places accelerated wear on consumable items such as brake discs and pads, suspension components, and the drivetrain. The MOT history is sparse, with only three tests recorded over a two-year period, and contains a clear data anomaly: a pass recorded on 2024-06-18 at 143,204 miles, which is physically impossible given the subsequent lower readings. This clerical error in the record makes a precise longitudinal analysis difficult, but the consistent high annual mileage implied by the valid entries remains a key factor for a buyer. A buyer must conduct an in-depth inspection of all electrical systems, particularly verifying the permanent resolution of the engine management light (MIL) and SRS warning lamp faults that caused the August 2025 failure. The slightly damaged offside obligatory mirror, while a minor advisory, should be checked for sharp edges. Given the high mileage, special attention is required to the braking system for uneven disc wear or binding calipers, the suspension for worn bushes or coil springs, and the exhaust for corrosion. The structural integrity appears unremarkable from the record, but the high usage combined with the past electrical neglect warrants a thorough pre-purchase examination of all drivetrain and safety-critical components.
