2010 Mercedes-Benz CLS 3.0L Diesel · KM10 RHE

Recurring issues with wheel bearings, brake components, and suspension linkages define the mechanical profile of this Mercedes-Benz CLS. The most recent test on 2023-09-06 resulted in a pass, but it continued a trend of advisories regarding front wheel bearing play and tyre wear. The history shows a pattern of progressive wear in the braking system and steering/suspension components, with previous failures involving both brake pad wear indicators and significant corrosion on the rear brake pipes in 2019. While the vehicle has passed its recent inspections, the repetition of advisories for wheel bearing play across 2022 and 2023 suggests these components have not been renewed and are nearing the end of their functional life. The vehicle has covered 117,431 miles over its sixteen-year lifespan, averaging approximately 7,339 miles per year. This represents a relatively low annual mileage for a vehicle of this age and class, which typically suggests more localized or short-distance usage rather than high-speed motorway cruising. Mechanically, this level of usage means that while the drivetrain may have lower cumulative stress, components such as suspension bushes, brake calipers, and rubber seals are more susceptible to age-related degradation and environmental corrosion rather than purely mileage-based wear. A prospective buyer should pay close attention to the chassis and braking hardware during a physical inspection and test drive. The history of corroded brake pipes, specifically the offside front and nearside rear issues recorded in 2020 and 2019, necessitates a thorough visual check of the entire brake line network for signs of surface rust or weeping. During the test drive, listen for any rhythmic humming or grinding noises that increase with vehicle speed, which would indicate the ongoing play in the front wheel bearings noted in recent years. Additionally, monitor the brake pedal for any sponginess or unevenness, given the history of thin pads and pitted discs. Suspension and steering integrity should also be a primary focus. The record indicates previous issues with the offside front lower suspension arm ball joint and track rod end dust covers. On the road, listen for knocks, clunks, or knocks when driving over uneven surfaces or turning the steering wheel at low speeds, as these are classic symptoms of worn ball joints or suspension bushes. The advisory regarding the nearside rear tyre being worn on the edge also warrants a check of the rear alignment to ensure there is no excessive camber or toe-in issues that could lead to premature tyre degradation.
