2018 Mercedes-Benz Vito 114 Bluetec Tourer Select 2.1L Diesel · KO18 TWM

The most recent MOT test on 2025-05-12 confirms the vehicle passed without defects, though it follows an unusual consecutive failure on 2025-05-11 at just ten miles less. This anomaly suggests either a temporary administrative oversight or a last-minute rectification of a non-recorded issue. Beyond this, the trend over the past four years remains stable, with no recurring advisories or failures beyond the isolated 2025 repeat. The vehicle has not undergone an MOT since May 2025, placing it 14 months past its due date, which is a significant gap for a diesel vehicle where emissions systems and fluid levels can degrade over time. The mileage progression reveals an unusually high annual average of approximately 14,656 miles, with no extended periods of low usage. Between 2022 and 2023, the vehicle accumulated 36,620 miles in a year, and another 23,222 miles between 2023 and 2024—a pattern that implies consistent heavy usage. The absence of any advisories or failures in earlier tests suggests the previous owner maintained the vehicle adequately, though the rapid mileage accumulation may have accelerated wear on high-use components like suspension bushes, coil springs, and brake calipers. The lack of gaps in mileage also rules out prolonged storage, which could have masked corrosion or fluid degradation. Given the stable MOT history, a buyer should prioritise an inspection of the suspension system, particularly the rear axle where binding calipers or worn bushes could have gone unnoticed without a failure. The high mileage warrants close examination of brake discs for lateral cracking or uneven wear, as well as the condition of the exhaust system for leaks or corrosion, particularly around the catalytic converter and diesel particulate filter. The absence of advisories does not preclude gradual wear on the drivetrain or transmission, so fluid levels and condition should be verified. The 14-month MOT gap also necessitates a check of diesel fuel quality, as water contamination or particulate buildup can occur in stored vehicles, even those in regular use.
