2015 Mercedes-Benz A-Class 2.1L Diesel · RO15 BYN

The vehicle passed its most recent MOT on 31 January 2026 at 83,706 miles, but the test flagged corrosion on both front brake pipes, covered in grease — a clear sign of deferred maintenance. This is the first defect recorded in over a year, yet it reveals a pattern of neglect in brake system upkeep. The absence of defects in the 2025 test suggests the issues were not present then, meaning the corrosion developed rapidly in the last 12 months, indicating a worsening trend rather than stable condition. Mileage accumulation is consistent with average annual use for its age, averaging 7,600 miles per year since registration. The gaps between tests are regular, with no unexplained jumps or long periods without testing. The 6,615-mile increase from February 2025 to January 2026 is normal, and the 2024 test showed tyre wear that was already approaching legal limits, suggesting the vehicle was driven with marginal tread. There are no signs of odometer tampering or irregular usage patterns. A buyer must inspect the front brake pipes immediately for active corrosion, especially where grease has been applied as a temporary cover — this is not a fix but a concealment, and the pipes may be near failure. The rear brake pads were noted as thin in early 2023, and with no subsequent replacement recorded, they may now be worn beyond safe limits. The front tyres flagged in 2024 as worn on the edges indicate possible suspension misalignment or worn bushes, which should be checked for uneven wear patterns and component play. The vehicle has no history of structural rust or exhaust failures, but the brake pipe corrosion suggests moisture exposure and poor underbody care, so a full underbody inspection for rust on suspension mounts, fuel lines, and chassis members is essential.
