2005 Mercedes-Benz CLS 5.0L Petrol · RX05 YGV

Chronic instability regarding the front wheel bearings defines this vehicle's mechanical record, with slight play noted consistently from 2019 through to the most recent pass on 2025-08-22. This recurring advisory, combined with a 2022 failure for a lower suspension arm ball joint dust cover and worn bushes, indicates a pattern of gradual wear in the front-end running gear. While the vehicle has maintained a passing status in recent years, the persistence of these specific defects suggests that certain components are reaching the end of their service life without being replaced. The recorded mileage of 101,721 miles is low for a twenty-one-year-old vehicle, averaging approximately 4,844 miles per year. Such a low annual accumulation often correlates with the types of defects seen in the MOT history, specifically the corrosion and pitting of the brake discs and the perishing of tyre sidewalls noted in 2022 and 2024. These symptoms are typical of a vehicle that may have spent extended periods stationary, leading to surface oxidation on braking components and the degradation of rubber compounds. During a physical inspection, particular attention should be paid to the braking system and front suspension. The 2024 advisories for deteriorated rear brake hoses and corroded, pitted brake discs necessitate a check for pedal judder or a spongy feel during braking. The history of suspension arm wear and ball joint failure means the test drive should focus on listening for knocks or clunks when traversing uneven surfaces or during low-speed manoeuvring. The recurring wheel bearing play should be monitored for an audible humming or droning noise that increases with vehicle speed. Additionally, the engine bay should be inspected for evidence of the oil leak flagged in 2022 to determine if the leak has persisted or been resolved. Finally, the offside front headlamp lens should be checked for the product buildup noted in the latest test to ensure light projection remains sufficient for night driving.
