2010 Mercedes-Benz CLS 3.5L Diesel · YK10 RZX

This 2010 Mercedes-Benz CLS has a clear and worsening pattern of brake and suspension wear that demands urgent attention before purchase. The most recent MOT in February 2025 was a pass, but only after a failed attempt five days earlier. That failed test revealed excessively corroded brake pipes on both front wheels—a safety-critical issue—along with excessive play in the offside front track rod end ball joint. The vehicle was also brought back with a non-opening boot, suggesting either a mechanical fault or poor maintenance attention. Five days later it passed, but the underlying corrosion and suspension wear remain. The brake system shows a consistent deterioration over the past two and a half years. In September 2022, both front brake pipes were already corroded and rear pads were wearing thin. By January 2024, the front pipes had worsened and rear pads had dropped below the legal minimum thickness. By February 2025, the front pipes were excessively corroded—a step beyond mere surface corrosion—and both rear service brakes are now binding, indicating either worn pads, contaminated fluid, or seized callipers. Binding brakes reduce stopping power and increase stopping distance, a direct safety risk.
