2015 Mercedes-Benz Sprinter 2.1L Diesel · KJ15 OHF

The Sprinter’s MOT record shows a vehicle that has remained road‑worthy year after year, with only minor advisories and no outright failures, but the pattern of wear‑related notes from 2018 onward highlights components that are now approaching the end of their service life. The latest test on 10 January 2026 confirmed a pass, yet it recorded a front tyre worn to the legal limit, a damaged windscreen and a rear reflector that is only half‑effective, alongside routine advisories for the parking‑brake lever and rear‑light indicators. This combination of a clean pass and a handful of wear items suggests a generally sound chassis but a need to address ageing suspension and braking parts before they become safety concerns. At 143 430 mi the Sprinter averages roughly 13 000 mi per year, which is well above the mileage typical for a light commercial vehicle of its age. The consistent annual MOTs indicate the vehicle has not spent prolonged periods off the road, meaning the high kilometre count translates into cumulative stress on the suspension bushings, wheel bearings, brake discs and tyre tread. Such mileage accelerates the natural wear cycle of these wear items, so the advisories recorded in 2018 for slightly worn front upper shock‑absorber bushes, front brake disc wear and front wheel‑bearing play are consistent with the mileage profile and should be expected to have progressed further. When inspecting the suspension, concentrate on the front upper shock‑absorber bushes and the associated coil‑spring mounts. Listen for any knocking or clunking when driving over potholes or speed bumps, and feel for any looseness in the steering column that could indicate bush wear advancing to a failure point. The front wheel bearings, flagged for slight play in 2018, should be examined for a low‑frequency hum that changes with steering angle or load; any increase in noise or roughness when turning suggests the bearings may need replacement. The brake system, noted for a front disc that was “worn, but not excessively” in 2018, warrants a thickness check and a road test for pedal feel – pulsation, squealing or a longer stopping distance would point to disc thinning or uneven wear that now demands resurfacing or replacement. Finally, the front tyre on the off‑side is already at the legal tread limit, so budgeting for a new tyre set is prudent before the next MOT. Verify that the parking‑brake lever now holds the vehicle securely on a gradient, as the advisory for adjustment indicates it may have been marginal. The windscreen damage should be inspected for cracks that could spread, and the rear reflector’s reduced surface area should be replaced to ensure adequate rear‑light visibility. While the indicator lenses are merely discoloured, swapping them will restore full compliance. Addressing these specific items will bring the Sprinter back to a condition where its high mileage no longer presents an imminent mechanical risk.
