2008 Mercedes-Benz CLS 3.0L Diesel · SR08 ACY

The vehicle is currently roadworthy but the maintenance history reveals a pattern of reactive repairs rather than proactive preventative care. While the most recent test in August 2025 at 132,639 miles was a pass, the advisories for thin rear brake pads, worn discs, and three tyres nearing the legal limit indicate the owner only addresses components once they approach failure thresholds. The overall trend is stable in terms of passing, yet recurring issues with the braking system and electronics persist across the last three years. At 132,639 miles over 18 years, the CLS has covered an average of approximately 7,400 miles per year, which is consistent with typical low-impact annual use. The data shows consistent usage, with roughly 5,200 miles driven between the July 2023 and 2024 tests, and another 4,100 miles leading to 2025. This steady mileage suggests the vehicle is not sat for long periods, though the age explains the degradation of rubber and metal components. A buyer must conduct a thorough inspection of the braking system, as the record shows persistent corrosion on the nearside front brake pipe and offside front brake hose dating back to 2023. The parking brake failed efficiency in both 2023 and 2024, suggesting the mechanism may be prone to adjustment or wear. Additionally, the illuminated glow plug warning light has been a constant fault since at least 2023, indicating a persistent sensor or engine management issue that remains unaddressed despite testing. Suspension components require close attention following the failure of the offside front suspension arm ball joint in 2023. The 2024 test also flagged cracking and perishing on the inner sidewalls of the tyres, which often points to alignment issues or age-related rubber failure. The oil leak around the sump area noted in 2024 should be visually verified to ensure the sump gasket or front seal has not worsened into a significant leak.
