2017 Mercedes-Benz Vito 1.6L Diesel · WU17 EFE

The 2017 Mercedes-Benz Vito presents a mixed roadworthiness picture where recent compliance masks a pattern of escalating concerns over the past two years. The most recent MOT conducted on September 11, 2025 resulted in a clean pass with no defects noted, which appears to represent a temporary stabilization after several earlier difficulties. Earlier in 2023, the vehicle required attention when both nearside and offside front brake discs were reported as worn (advisory level), accompanied by a minor damage to the nearside obligatory mirror. A more significant setback occurred in September 2022 when the vehicle failed its MOT entirely due to a dangerously thin offside rear brake pad thickness below 1.5 mm and excessive movement in the parking brake lever, alongside a broken nearside door mirror and confirmation of tire pressure monitoring system (TPMS) activation. Despite these setbacks, the latest 2025 assessment shows the car back on track, though the historical sequence suggests underlying systemic issues rather than isolated incidents. At 87,882 miles for a nine-year-old vehicle, the average annual mileage of approximately 9,765 miles falls within the expected range for its age, indicating neither unusually high nor suspiciously low usage patterns. The consistent passing of MOTs since 2020 reflects that routine servicing kept the major systems operational during the intervening period, yet the gap between the 2022 failure and the 2025 pass spans nearly three years without further recorded faults. There is no evidence of sudden acceleration in wear such as rapid mileage spikes or concentrated abuse events; instead, the progression appears gradual with the 2022 failure representing the first serious red flag followed by a longer interval before another clean result. This steady but uninterrupted progression from warning to resolution does not eliminate concern about the nature of the underlying problems that triggered the 2022 failure. The adjacent front brake discs have been repeatedly flagged across the 2023 MOT, suggesting potential wear through normal braking cycles but also raising questions about brake pad material quality or insufficient replacement intervals given their repeated appearance. On a test drive, the buyer should monitor for any pulsing or spongy sensation in the brake pedal, especially under hard stops, as this could indicate deeper caliper or master cylinder issues stemming from the repeated disc advices. The offside rear brake pad thickness being below 1.5 mm at the time of the 2022 failure represents a critical safety threshold; even though the current record shows a pass, the absence of a subsequent brake pad measurement would be a prudent verification point. Additionally, the nearside obligatory mirror damage noted in 2023 warrants visual inspection for frame-related mounting hardware integrity, as corroded or loose mirror supports may contribute to long-term alignment stress. The persistent TPMS activation throughout the record indicates the wheel speed sensors remain functional despite the 2022 failure, so this particular item is no longer a source of immediate fault. Based on the documented advisories, the buyer should prioritize a thorough inspection of the brake subsystem, focusing specifically on caliper operation, brake line routing, and pad condition, particularly on the side that showed the worst degradation in 2022. The parking brake mechanism requires independent verification of lever free play and hydraulic function, as the 2022 failure indicated incorrect adjustment that could recur if the system was not fully reconditioned. The mirror assembly should be checked for secure mounting bolts and whether the optical path remains clear, as a broken mirror often signals broader chassis stress points. Because the vehicle has accumulated nearly 88,000 miles, all other consumable components including suspension bushings, ball joints, and brake fluid should be examined for signs of accelerated wear, particularly in areas previously flagged for advisory status. Given the intermittent nature of the 2022 failure and the clean results since then, the car is technically roadworthy today, but the history necessitates a detailed pre-purchase examination before committing to purchase.
