2009 Mercedes-Benz B-Class 2.0L Diesel · P30 JAS

The vehicle most recently passed its MOT in January 2026, though the overall maintenance trend indicates a period of accelerating wear on critical chassis components. The history shows a pattern of suspension failure, with the nearside front suspension arm ball joint requiring replacement in 2024 and the offside front following suit in 2026. The emergence of multiple advisories regarding the braking system and shock absorbers suggests that the vehicle is entering a phase where several age-related consumables will require simultaneous attention to maintain roadworthiness. With a recorded mileage of 57,167 miles over seventeen years, the vehicle has averaged approximately 3,363 miles per year, which is significantly below the national average. While this low mileage suggests reduced wear on the drivetrain and engine internals, it often introduces a different set of mechanical risks associated with prolonged periods of inactivity. Low-usage vehicles are more prone to the degradation of rubber components, the accumulation of surface corrosion on brake discs, and the chemical breakdown of essential fluids regardless of the distance travelled. During a physical inspection and test drive, particular attention must be paid to the front suspension and braking system. The reported misting of the offside front shock absorber indicates a failing seal; listen for knocks or feel for excessive bouncing over uneven surfaces, as this will eventually lead to poor tyre contact and reduced stability. The pitted and scored condition of the front brake discs, combined with thin pads, suggests that the braking system is suffering from both wear and atmospheric corrosion. A test drive should be used to detect any brake shudder or grinding noises, and the buyer should budget for a full front brake overhaul. Given the low annual mileage, it is imperative to verify that the vehicle has been serviced based on time intervals rather than mileage alone. Inspect the tyre sidewalls for fine cracking or perishing, as tyres can lose structural integrity over time even if the tread remains legal. Check for binding brake calipers, which often occur when a vehicle stands for long periods, and assess the health of the 12V battery. Finally, examine the windscreen for the recorded damage to ensure it has not developed into a larger crack that could compromise the structural integrity of the glass or obstruct the driver's field of vision.
