2010 Mercedes-Benz CLS 3.0L Diesel · FD10 RCV

The vehicle most recently passed its MOT on 23 October 2025, though it carries an advisory for a worn and perished offside rear tyre. Looking at the broader history, the maintenance trend is concerning due to a recurring pattern of brake pipe corrosion and tyre degradation. Multiple failures between 2021 and 2024 regarding excessively corroded brake pipes across various corners of the chassis indicate a systemic issue with corrosion management, suggesting that repairs may have been reactive rather than preventative. With a recorded mileage of 52,642 miles over sixteen years, this vehicle has averaged approximately 3,290 miles per year. This is exceptionally low for a Mercedes-Benz CLS and suggests the car has spent significant periods standing or has been used for very short journeys. While low mileage reduces wear on the engine and gearbox, it often introduces specific risks such as the perishing of rubber components, the accumulation of moisture in the braking system, and the degradation of fluids regardless of the distance travelled. A prospective buyer must pay close attention to the braking system. The history of repeated brake pipe failures and advisories for pitted and scored rear discs is a red flag for a vehicle that has suffered from standing corrosion. During a physical inspection, check for any signs of surface rust on the remaining brake lines and ensure that the brake pedal feels firm and consistent. On a test drive, listen for any grinding sounds or feel for brake shudder, which would indicate that the previously noted disc pitting has worsened or that the calipers are beginning to bind due to inactivity. The recurring advisories regarding tyre perishing and cracking, specifically on the offside rear, confirm that the rubber has aged out of its usable life. Inspect all four tyres for sidewall cracking and check the date codes to ensure they are not older than six years, regardless of the remaining tread depth. Additionally, given the low annual usage, verify the service history for calendar-based oil changes and coolant flushes, as these fluids degrade over time. Check the 12V battery health and inspect the central exhaust mounting to ensure the previous advisory has been fully rectified and the system is secure.
