2009 Mercedes CLS 3.0L Diesel · KR09 NBX

The vehicle is currently roadworthy following its most recent test, but the data reveals a worsening trend in braking system integrity. While it passed in October 2025 at 109,980 miles, it had failed just one week prior at 109,921 miles. This failure highlighted excessive corrosion on both front brake pipes and significant play in the nearside front track rod end. The presence of deteriorated rear brake hoses and a detached exhaust hanger on the passing certificate suggests that while immediate faults were addressed, maintenance remains reactive rather than preventative. At 17 years old, the recorded mileage of 109,980 miles represents an average usage of approximately 6,470 miles per year. This is consistent with low-intensity usage for a luxury saloon of this era. The history shows consistent intervals with roughly 4,000 miles driven between September 2023 and October 2024, and another 4,500 miles in the following year. However, the low annual mileage has not prevented age-related degradation of rubber components and corrosion of metal lines, as seen in the recurring failures. A buyer must conduct a thorough physical inspection of the braking system, specifically checking for further corrosion on the front pipework. The record shows corrosion noted in 2022 that escalated by 2025, indicating a long-term vulnerability to environmental factors or fluid ingress. The front suspension should be scrutinized for component wear, as the track rod end recently failed for excessive play. Additionally, the detached exhaust hanger and the deterioration of the rear brake hoses require a close look at the under-tray to ensure the exhaust system is secure and the hydraulic lines are not nearing imminent failure.
