2009 Mercedes-Benz B-Class 2.0L Diesel · FG09 YEE

A consistent history of minor maintenance oversights defines the roadworthiness record of this 2009 Mercedes-Benz B-Class, punctuated by recurring tyre and braking interventions across its timeline. The vehicle secured a clean pass on 2018-05-02, which successfully rectified a failure from the previous day for a severely weakened central rear brake disc, dangerously thin rear brake pads below 1.5 millimetres, and a bald nearside front tyre. Earlier testing cycles show a similar trend of friction component degradation, including a dangerous failure in 2013 for a tread-depleted nearside rear tyre alongside multiple advisories from 2014 noting scored brake discs across both axles, a worn offside front tyre, and a light oil misting on the offside front shock absorber. Accumulating 113,116 miles over its seventeen-year lifespan yields an average of approximately 6,654 miles per year, representing a typical domestic usage profile for a compact MPV of this era. This steady accumulation prevents the accelerated wear associated with high-mileage fleet use, though it also means consumables have been subjected to continuous seasonal thermal cycles. Testing intervals remain generally regular, apart from a tight sequence in the spring of 2013 and spring of 2015 where retests or additional checks occurred close together, and multiple inspections noted that under-trays and engine covers obscured parts of the underside and engine bay from standard visual assessment. On the test drive, prospective buyers must pay close attention to the braking system and front axle suspension given the historical pattern of disc wear, pad thinning, and shock absorber misting. Listen carefully for any knocking, clunking, or grunting noises from the front suspension over speed humps or rough patches, which would indicate degraded dampers or worn wishbone bushes. Check for any steering pull or vibration through the brake pedal when decelerating firmly from speed, ensuring that the previously neglected brake discs and pads have been replaced with quality components that do not suffer from thermal warping or uneven clamping. Underneath the car, verify that the under-trays are removed during a ramp inspection to properly scrutinize the brake lines, suspension mountings, and subframe areas that were previously hidden from the MOT tester's view by factory plastic guards. Inspect the front shock absorbers specifically for any active fluid leaks or dampness around the piston rods, as the 2014 advisory for oil misting indicates a component that was already beginning to weep. Confirm that all four tyres match in quality and possess healthy tread depths well above the legal minimum, addressing the historical tendency for this vehicle to run tyres down to or below the legal threshold.
