2008 Mercedes-Benz B-Class 1.7L Petrol · SD58 FDJ

A pattern of significant mechanical and safety failures between 2021 and 2022 has transitioned into a period of stability, with the most recent test on 25 August 2025 returning a pass with no defects recorded. The record shows a concentrated cluster of issues involving critical safety components, including dangerous brake wear and worn suspension joints, but the subsequent three years of clean passes suggest these specific defects were addressed and have not recurred. The recorded mileage of 107,529 miles is low for an eighteen year old vehicle, averaging approximately 5,974 miles per year. Such a low annual accumulation often indicates a vehicle that has seen lighter duty or experienced periods of inactivity. Mechanically, this usage profile shifts the risk from high-mileage drivetrain wear toward the degradation of rubber and plastic components, as evidenced by the previous records of perishing tyres and failing suspension joints. Attention should be paid to the front suspension and braking system given the dangerous failure of brake pads and the excessive wear of both nearside and offside front suspension arm ball joints in 2022. During a test drive, listen for knocking or clunking sounds when traversing uneven surfaces or during low-speed manoeuvring, as these can indicate that the replacement ball joints are wearing or that other suspension linkages are deteriorating. Check for any vibration or judder through the brake pedal to ensure the braking system is operating smoothly following the previous critical wear. The history of an oil leak and a blow from the exhaust front sleeve requires specific verification. Inspect the engine bay for fresh oil misting or residue and check the ground beneath the vehicle for leaks, as oil leaks noted in 2021 may have persisted or evolved. Listen for an abnormal rasp or loud drone from the front of the exhaust system while idling or accelerating to confirm the exhaust sleeve advisory from 2022 was permanently rectified. Finally, examine the tyres for any signs of sidewall cracking or perishing, which was previously flagged on the nearside rear.
