2010 Mercedes-Benz Vito 2.1L Diesel · WN60 UXY

A persistent, multi-year history of coolant leaks stands as the defining mechanical issue for this Mercedes-Benz Vito, appearing consistently across the 2019, 2020, 2023, and 2025 tests, culminating in its most recent pass on 16 October 2025. While the vehicle has successfully secured passes in its latest outings, the recurrence of this fluid loss alongside recurring lighting defects, a past SRS warning lamp failure, and dual seatbelt mechanism failures recorded during a 2022 test shows a mixed track record of roadworthiness rather than a completely stable one. Accumulating just 67,200 miles over its sixteen years on the road yields an average of roughly 4,200 miles annually, representing a significantly lower-than-average usage pattern for a commercial-derived passenger vehicle. This light annual mileage does not point to long-term storage gaps, as testing occurred annually without interruption, but it does mean components have experienced shorter journeys and potentially frequent urban stop-start conditions. Low-mileage utility vehicles often encounter specific mechanical stress from localized running rather than highway momentum, making a close inspection of auxiliary systems essential. When inspecting the vehicle on a test drive, the persistent coolant leak advisory demands immediate investigation of the engine bay, water pump, radiator matrix, and hose connections to identify any active dripping or crust residue. Prospective buyers should check the coolant expansion tank for oil contamination, verify that the temperature gauge remains stable under load, and listen closely for any unusual engine noises or rough idling. Additionally, the history of lighting advisories, including discoloured indicator lenses and inoperative daytime running lamps, requires a thorough operational check of every exterior bulb, while the prior SRS warning lamp and rear seatbelt failures necessitate testing all passenger restraint retractors and confirming that the dashboard warning lights extinguish correctly upon startup.
