2021 Mercedes-Benz Sprinter 314 Progressive CDI 2.1L Diesel · SV71 APU

The vehicle’s most recent MOT test on 2025-12-11—just seven months ago—confirms it passed without any recorded defects, despite the unusual dual entry (one pass, one fail at identical mileage). This suggests the test centre may have encountered a temporary administrative error, as no mechanical issues were logged. The preceding MOT in December 2024 at 116,240 miles also passed without failings, indicating a stable roadworthiness trend over the past year. However, the lack of advisories or defects does not preclude hidden wear from the high mileage accumulation, particularly in high-stress components like suspension bushes, coil springs, and brake calipers. The recorded mileage of 145,296 miles over roughly 4.5 years equates to an average of 32,064 miles annually, which is significantly above the UK average for a vehicle of this age. This rapid accumulation implies either consistent commercial use or prolonged periods of active operation, both of which accelerate wear on consumables like tyres, brake pads, and clutch components. The gap between tests—exactly one year apart—is standard, but the absence of any advisories in either 2024 or 2025 raises questions about whether minor issues were overlooked or consistently addressed privately. The lack of a pre-MOT inspection record further complicates assessing whether critical components were serviced between tests. Given the high mileage and the vehicle’s age, a buyer should prioritise a thorough inspection of the suspension system, particularly the rear axle where binding or uneven wear is common in Sprinter models. The brakes—especially the rear calipers and discs—should be checked for uneven wear or corrosion, as high mileage often correlates with reduced stopping efficiency. Structural integrity of the chassis and subframe should also be examined for signs of fatigue or corrosion, particularly around welds and wheel arches. The engine bay should be scrutinised for oil leaks, as the CDI system is prone to turbocharger and EGR valve wear at this mileage. Finally, the exhaust system should be inspected for rust or cracks, as these failures often go unnoticed until they compromise emissions or structural integrity.
