2014 Mercedes-Benz Viano 2.1L Diesel · OY64 ENF

The vehicle is currently roadworthy, but the maintenance trend indicates a reactive approach to repairs rather than proactive prevention. The most recent test in September 2025 at 129,170 miles showed a pass following a failure just eight days prior. While the vehicle has cleared the MOT requirements, the transition from a significant failure involving multiple tyre-related defects to a clean pass suggests that the previous owner only addressed mechanical issues once they threatened the vehicle's legal status. The mileage pattern is consistent with a twelve-year-old commercial vehicle, averaging approximately 10,700 miles per year. Between September 2024 and September 2025, the vehicle covered 10,653 miles, which aligns perfectly with its historical average. This steady usage suggests the drivetrain and primary components are subjected to regular loads rather than long periods of stagnation. However, the accumulation of over 129,000 miles means that wear on suspension components and bushings is expected despite being monitored between annual inspections. A buyer must conduct a close physical inspection of the suspension system, as the nearside rear suspension bellows were flagged as damaged in 2025. Although this was not to excess at that time, air suspension components on Vianos are prone to progressive degradation and sudden failure. The 2025 failure also highlighted uneven tyre wear on the inner edges, which often points to an alignment issue or worn suspension bushes. You should check for further irregular tyre wear and ensure that the steering geometry is not bent or out of specification. The brake system requires specific attention following the 2024 failure regarding the worn brake pedal anti-slip provision. While that specific part was replaced, it indicates a potentially overlooked safety item. Inspect the condition of the brake discs and check for scoring or deep pitting, which could indicate binding calipers. Given the age and mileage, the chassis should also be examined for structural corrosion, particularly around the sills and mounting points, as the record does not explicitly clear any structural advisories to date.
