2011 Mercedes-Benz CLS 3.0L Diesel · WLZ 811

The most recent MOT on 2026-04-15 recorded multiple brake-related issues, including worn, pitted brake discs, thin front and rear brake pads, and corroded rear brake pipes. These defects were also noted in the prior MOT on 2026-04-08, which resulted in a failure. The same brake disc and pad issues persisted between the two inspections, suggesting ongoing wear or incomplete repairs. The 2026-04-08 failure also highlighted a fractured offside front coil spring and a damaged anti-roll bar dust cover, which were not previously recorded, indicating emerging suspension concerns. The pattern of recurring brake wear, combined with new suspension faults, points to a worsening condition. Brake discs and pads typically degrade gradually, but the lack of improvement between the two 2026 inspections implies either unresolved repair work or continued heavy use. The fractured coil spring and anti-roll bar dust cover represent more severe issues that could compromise handling and safety, particularly if left unaddressed. The vehicle’s mileage of 210,214 miles at 15 years old equates to roughly 14,014 miles annually, which is high for its age. This suggests frequent use, potentially accelerating wear on brakes, suspension, and drivetrain components. However, the absence of major defects in 2025 and 2023 MOTs indicates periods of stable performance, though the recent escalation in issues raises concerns about long-term reliability.
