2008 Mercedes-Benz CLS 3.0L Diesel · L77 ABO

The vehicle most recently passed its MOT on 1 December 2025, though the overall maintenance trend indicates a gradual decline in mechanical condition. While the car has passed the majority of its tests, the failure in November 2025 regarding critical suspension components and windscreen washers, combined with persistent recurring advisories, suggests that the vehicle is entering a phase of increased mechanical attrition. The pattern of the records indicates that several defects are being monitored as advisories over multiple years rather than being proactively rectified, which may point to a reactive approach to maintenance. With a recorded mileage of 95,911 miles over an eighteen year period, the vehicle has averaged approximately 5,328 miles per year. This is significantly lower than average for a luxury saloon of this vintage. While this implies reduced wear on the internal engine components and drivetrain, such low usage often correlates with periods of standing, which can be detrimental to rubber components, seals, and braking systems. The buyer should be aware that low mileage does not necessarily equate to a pristine mechanical state, as calendar-based degradation can be as impactful as mileage-based wear. A primary area of concern is the recurring advisory regarding corroded brake pipes, which has appeared consistently since 2022. The specific mention of pipes being covered in grease is a common indicator of attempts to mask corrosion or prevent further decay. During a physical inspection, it is imperative that the undertrays are removed to allow a full inspection of the brake lines for pitting, swelling, or leaks. Additionally, the recent replacement of the front lower suspension arm ball joints should be verified via invoices. On a test drive, listen for any remaining clunks or knocks over uneven surfaces and check for steering vagueness, which would suggest further wear in the suspension bushes or upper arms. Given the low annual mileage, particular attention must be paid to the condition of the tyres; check the sidewalls for perishing or hairline cracking regardless of the remaining tread depth. Inspect the brake discs for heavy surface corrosion or evidence of binding calipers resulting from prolonged inactivity. It is essential to verify the service history to ensure that engine oil and other critical fluids have been changed based on time intervals rather than mileage alone, as degraded oil can lead to premature sludge build-up. Finally, check the condition of the exhaust mountings, as this has been a persistent advisory and may lead to excessive vibration or exhaust leaks if the rubber has perished.
