2010 Mercedes-Benz Sprinter 2.1L Diesel · WM10 CWN

Chronic rear anti-roll bar wear is the defining mechanical theme of this Sprinter, with both the nearside and offside rear D bushes flagged at every test since September 2022 and showing no sign of resolution across three consecutive advisories. While none of the entries have yet tipped into the failure bracket, the persistence of the same components on the same axle over a two-year window strongly suggests the bushes are nearing the end of their useful life and will likely cross into a Major defect at the next assessment. The September 2024 test recorded a Major failure for an inoperative front registration plate lamp, an electrical fault that was subsequently rectified before the vehicle returned eight days later to pass. Body corrosion was also noted as an advisory at both 2024 visits, an early indicator that structural integrity should be examined closely given the vehicle's commercial heritage and exposure to load-bearing stress. With 174,429 miles accumulated over sixteen years, the Sprinter averages around 10,900 miles annually, a figure consistent with steady light-commercial or shuttle use rather than intensive multi-shift operation. There are no extended gaps in the testing record, confirming continuous road use rather than long periods of standing that would raise concerns over seized brakes, deteriorated rubber seals, or degraded diesel particulate filters. At this mileage bracket on a 2010 OM-series diesel, internal engine wear, turbo actuator function, injector balance, and dual-mass flywheel integrity become pertinent considerations, even though none of these items fall under MOT scope. The mileage also places the vehicle firmly within the wear zone for suspension consumables, steering components, and rear axle bearings, all of which align with the recurring anti-roll bar advisories observed in the history. A prospective buyer should treat the rear anti-roll bar D bushes as an imminent replacement item and budget for the work, which on a Sprinter of this generation typically involves dropping the rear anti-roll bar to press in new polyurethane or rubber bushes. On a test drive, listen for clonking or knocking noises from the rear axle over speed humps and uneven surfaces, particularly during direction changes, as worn D bushes allow the bar to articulate loosely within its brackets. Check for excessive body roll through roundabouts and observe whether the rear end feels unsettled over undulating roads, all classic symptoms of compromised anti-roll bar links. Body roll in commercial vans tends to be pronounced anyway, so any marked increase beyond the expected level is a red flag warranting closer inspection of the rear suspension as a whole. Given the body corrosion advisory flagged in 2024, a thorough underbody examination is essential, paying particular attention to the rear crossmember, wheel arches, sills, jacking points, and the subframe mounting areas where road salt and moisture collect. Tap-test suspect panels for thin or crusty metal, and inspect the load floor edges and door bottoms for bubbling paint or surface scale. The recurring nearside side repeater lens defect, present at every test in the record, suggests a cracked or perished lens that has never been replaced; this is a trivial fix but worth noting as a marker of minor cosmetic neglect. Finally, verify full electrical function of all exterior lamps including registration plate illumination, outline marker lamps, and side repeaters, as the 2024 failure for an inoperative plate lamp and the 2023 Prescribed item for an outline marker lamp indicate a pattern of minor electrical deterioration that may extend to other lighting circuits not specifically recorded at test.
