2009 Mercedes-Benz CLS 3.0L Diesel · GO51 DHU

The vehicle’s most recent MOT on 2026-06-09 confirmed roadworthiness but noted persistent issues including steering rack play, an oil leak, and headlamp alignment. These defects mirror findings from prior tests, indicating a stable but unresolved maintenance trend. While no critical failures were recorded, recurring corrosion on brake pipes and minor suspension play suggest ongoing exposure to environmental or mechanical stress. The absence of significant structural or drivetrain issues in the latest test is positive, but the pattern of minor faults implies routine upkeep rather than proactive repairs. The vehicle’s mileage of 86,863 miles at 17 years old equates to approximately 5,110 annual miles, a low figure that may reflect infrequent use or prolonged periods of inactivity. MOT records show consistent annual testing since 2023, with the 2023-06-12 failure highlighting severe brake pipe corrosion and tyre wear. Subsequent tests through 2024 and 2025 addressed some issues but failed to eliminate recurring problems, such as steering rack play and oil leakage. The 2024-06-11 test noted corroded rear brake discs, while the 2025-06-11 test flagged a deteriorated suspension ball joint dust cover. These gaps in maintenance suggest intermittent attention to critical systems. A buyer should prioritize inspecting the suspension components, particularly the nearside steering rack and front suspension ball joints, for excessive wear or replacement needs. Brake systems require scrutiny, focusing on corrosion of pipes and discs, as well as pad thickness. The oil leak, though non-critical, warrants investigation to prevent potential engine or transmission damage. Tyre condition remains a concern, given the 2023 failure due to worn edges, and current tread depth should be verified. Structural integrity appears unimpaired, but the history of brake pipe corrosion raises questions about long-term exposure to road salts or poor drainage.
