2014 Mercedes-Benz Viano 2.1L Diesel · GU64 ACZ

The vehicle is currently roadworthy, having passed its most recent MOT on 2 May 2026 at 479,011 miles with no defects recorded. The maintenance trend appears stable in the short term, as the last three tests since May 2024 have been clean passes. This follows a period of more frequent failures and advisories between 2019 and 2023, suggesting a recent improvement in how the vehicle is being maintained. The mileage is exceptionally high for a twelve year old vehicle, averaging nearly 40,000 miles per year. The accumulation has been rapid and consistent, with the odometer climbing from 185,341 miles in July 2020 to 479,011 miles by May 2026. This represents over 290,000 miles covered in less than six years. Such heavy usage typically accelerates wear on the drivetrain, suspension bushes, and engine internals beyond standard expectations. A buyer should prioritise a physical inspection of the chassis and underbody. The May 2023 test at 335,568 miles flagged corrosion on the front cross support beam and side steps. While not noted in recent tests, structural rust often progresses and requires verification to ensure the integrity of the frame. The braking system also shows a history of instability; the vehicle failed in May 2021 due to thin rear pads and an inoperative parking brake, and the parking brake barely met efficiency requirements again in May 2023. Given the extreme mileage, the buyer must verify the service history for timing chain or belt replacements and transmission fluid changes. The May 2019 failure for exhaust emissions suggests previous issues with the fuel or exhaust system that warrant a check for current smoke levels or catalytic converter efficiency. Inspecting for oil leaks and suspension play is essential, as the high-mileage profile makes these components prime candidates for imminent failure.
