2016 Mercedes-Benz B-Class 1.5L Diesel · FP66 YAG

The most recent MOT history for this 2016 Mercedes-Benz B-Class reveals a concerning pattern of repeated failures just before passing tests, with the vehicle failing twice in quick succession in both 2023 and 2022. The last successful test occurred on 24 March 2023, but the vehicle was already due for renewal by 24 March 2024—nearly two years ago. The lack of any recorded defects in these tests suggests the failures were likely procedural or administrative rather than mechanical, but the repeated near-failures indicate a lack of thorough pre-test maintenance. The most recent test was conducted at 77,777 miles, meaning the vehicle has not undergone an official inspection for nearly two years, which is well beyond the recommended annual check for vehicles of this age. The mileage progression shows a steady accumulation of approximately 7,778 miles annually, which is typical for a vehicle of this age and usage profile. There are no significant gaps or abrupt jumps in mileage between tests, ruling out prolonged periods of neglect or rapid wear. However, the consistent annual mileage suggests the vehicle has been in regular use without extended periods of inactivity, which could imply higher wear on suspension bushes, coil springs, and brake components. The lack of any advisory notes or defects in the MOT records also means there is no historical evidence of recurring issues like binding calipers, excessive corrosion, or drivetrain faults, but this does not preclude their presence. Given the absence of recorded defects, the most critical areas for an in-person inspection should focus on components that often fail without obvious warning signs. The suspension—particularly the rear coil springs and bushes—should be examined for uneven wear or sagging, as these are common points of failure in vehicles of this age and mileage. Brake discs and pads should be checked for uneven wear or glazing, as repeated near-failures could indicate past issues with binding calipers or inadequate fluid levels. Structural integrity, especially around the wheel arches and sills, should be scrutinised for corrosion, as this is a frequent cause of advisory notes in MOT tests. Additionally, the exhaust system should be inspected for leaks or excessive rust, as this is another area where failures can go unnoticed until they become serious. The lack of recent MOT tests also makes it prudent to verify the condition of the battery, fuel system, and electrical connections, as these are often overlooked but critical for roadworthiness.
