2009 Mercedes-Benz E 3.5L Diesel · OY59 BWC

A recurring pattern of brake pipe corrosion and oil leaks defines the mechanical history of this vehicle, despite a consistent record of passing its tests. The most recent inspection on 19 May 2026 resulted in a pass but highlighted that the front brake discs are now worn, pitted, or scored. This follows a trend of intermittent advisories regarding fluid leaks and structural corrosion of the braking system seen in earlier years, suggesting these are persistent areas of wear. The recorded mileage of 145,817 miles is typical for a vehicle of this age, averaging approximately 8,577 miles per year. This level of usage indicates that the drivetrain and chassis have been subjected to standard wear and tear. At this mileage, components such as suspension bushings, engine seals, and wheel bearings are typically reaching the end of their primary service life, which aligns with the various advisories recorded in the history. Particular attention should be paid to the braking system and suspension. The current advisory for pitted and scored front brake discs should be investigated for signs of pedal judder or increased stopping distances during a test drive. Additionally, the 2025 advisory regarding play in the nearside front lower suspension arm ball joint, combined with previous notes on wheel bearing play, means the buyer should listen for knocking or clunking sounds when traversing uneven road surfaces or a rhythmic humming noise at higher speeds. The recurring mention of a central front oil leak and previous corrosion on the brake pipes requires a physical inspection of the underbody. A test drive should include a check for any burning oil smells after the engine has reached operating temperature. The history of corrosion on the brake pipes, specifically those leading to the flexi-hoses and above the subframe, necessitates a close inspection of the lines for any new signs of oxidation or degradation that could compromise the structural integrity of the braking circuit.
