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

The Sprinter presents a stable and currently clean roadworthiness profile following its most recent test on 26 September 2025 at 62,780 miles, where the tester recorded zero defects. This outcome marks a clear improvement over the June 2024 test at 55,813 miles, which initially resulted in a failure before a successful retest on the same day. The progression from multiple advisories to a fully clean sheet suggests the previous owner addressed the flagged items promptly, indicating reactive but ultimately responsible maintenance behaviour in the last year. At roughly five years old, the recorded mileage of 62,780 miles equates to an average of approximately 12,556 miles per year. This is notably high for a large panel van of this age and points to sustained commercial or long-distance use. The 6,967-mile gap between the June 2024 and September 2025 tests is consistent with that annual rate, showing no prolonged periods of inactivity that might raise concerns about deterioration from standing. High annual mileage accelerates wear on consumables, suspension components, and drivetrain parts, meaning the clean 2025 result is a positive indicator of ongoing upkeep rather than low use. Despite the recent clean test, the June 2024 advisories warrant close physical inspection. The tester flagged both front brake discs as worn, pitted, or scored on inner and outer faces, a condition often linked to aggressive braking or deferred pad replacement under high-mileage use. A buyer should measure remaining disc thickness and check for lipping or heat cracking, particularly if the van has continued to cover significant miles since September 2025. The nearside front tyre advisory for cracking within the tread also raises a flag about age-related rubber degradation, especially if the tyres are original or have not been replaced recently. Inspect all four sidewalls and tread bases for perishing, and verify the age codes on each tyre. The windscreen stone chip noted offside upper in 2024 did not affect the driver's view and likely remains unrepaired. Examine that area carefully for any crack propagation, as temperature changes and road vibration can cause small chips to spread over time, particularly on large commercial van screens. The inoperative nearside rear registration plate lamp was a straightforward failure likely resolved by bulb replacement, but a quick function check of all exterior lighting remains prudent. Given the van's high annual mileage and commercial duty cycle, prioritise an underbody inspection for corrosion, suspension bush wear, and exhaust system integrity, as these components endure disproportionate stress in hard-worked vehicles.
