2007 Mercedes E 3.0L Diesel · BN07 HRD

The vehicle maintains a roadworthy status but the maintenance history reveals a concerning trend of reactive rather than proactive repairs. The most recent test in April 2024 at 151,566 miles passed with advisories for a worn front suspension arm ball joint with play and corroded rear brake pipes. This brake pipe issue is a recurring defect, having been flagged in 2022, 2023, and 2024, suggesting that previous owners merely cleaned or masked the corrosion rather than replacing the affected components. At 19 years old, the recorded mileage of 151,566 miles represents an annual average of approximately 8,000 miles, which is consistent with typical older executive-class usage. The data shows consistent use, with roughly 10,000 miles covered between March 2022 and April 2023, and another 10,000 miles in the following year. However, the failure in March 2022 due to a tyre with exposed cords and excessive oil leakage indicates a period lapse in basic safety inspections during that period. A buyer must conduct a thorough physical inspection of the chassis and braking system to assess the extent of the ongoing corrosion issues. The persistent mention of rear brake pipe corrosion across three years suggests significant degradation of the metal lines which could lead to a sudden hydraulic failure. The front suspension arm ball joint noted in 2024 requires immediate checking for movement, as play in these compromises steering precision and tyre life. Additionally, the engine oil leak reported in the 2022 failure should be monitored to ensure it has not worsened into a significant seal failure that requires an engine overhaul.
