2008 Mercedes-Benz B-Class 2.0L Diesel · RV08 HNA

Recurring issues with the nearside front outer drive shaft CV boot and a growing list of braking and tyre advisories define the mechanical profile of this Mercedes-Benz B-Class. The most recent MOT on 12 October 2024 shows a pass, but it follows a failure on the same date due to a split nearside front outer drive shaft CV boot. This specific component has appeared in various states of deterioration or failure across multiple tests dating back to 2021, indicating a persistent issue with the drivetrain's protective boots. Furthermore, the latest record introduces several new advisories regarding pitted or scored brake discs at both front and rear, thinning rear brake pads, and perishing rear tyres, suggesting a trend toward increased wear on consumable components. The vehicle has covered 55,564 miles over its 18-year lifespan, which equates to an average annual accumulation of approximately 3,087 miles. This is significantly lower than the typical UK average for a vehicle of this age. While low mileage can reduce wear on certain mechanical assemblies, the specific defects recorded—such as the cracking and perishing of tyres and the corrosion of rear coil springs noted in 2021—are often characteristic of vehicles that spend extended periods stationary or are driven infrequently. This usage pattern can lead to the degradation of rubber components and the onset of surface corrosion on metal parts that are not regularly cleaned by road use. Prospective buyers should pay close attention to the braking system and the drivetrain during a test drive. Given the advisories for pitted and scored discs alongside thinning pads, listen for any grinding noises during deceleration or a pulsating sensation through the brake pedal, which could indicate uneven disc surfaces. The repeated failures of the nearside front outer drive shaft CV boot necessitate a close inspection of the area for grease spray or torn rubber. On the road, listen for rhythmic clicking or popping sounds when turning the steering wheel at low speeds, which may signal that the CV joint itself has been compromised by the ingress of dirt following the boot failure. Suspension and tyre integrity also require scrutiny. The 2021 record flagged corroded rear coil springs and light oil misting from the nearside rear shock absorber; although not flagged in the most recent test, these areas should be visually inspected for heavy scale or active leaks. The recent advisories regarding perishing rear tyres suggest the rubber is losing its elasticity. During the test drive, check for any unusual vibrations or a tendency for the vehicle to wander, and inspect the sidewalls of the rear tyres for any further signs of cracking or structural degradation.
