2008 Mercedes-Benz E 2.1L Diesel · BF08 HDD

A history of significant structural and braking system failures defines this vehicle's MOT profile, specifically regarding corrosion and suspension integrity. While the most recent test on 15 April 2026 resulted in a pass with no defects, the record shows a pattern of serious issues, including a dangerous failure in 2022 due to invisible brake fluid and multiple major failures related to corroded brake pipes. The mechanical trend shows a period of instability between 2022 and 2024, where both the braking system and the rear coil springs required intervention, though the 2025 and 2026 results suggest these specific critical failures have been addressed. The recorded mileage of 52,197 miles over an 18-year period represents an unusually low annual average of approximately 2,900 miles. This low-intensity usage pattern is consistent with a vehicle that has spent significant time stationary or has been used only for very short, infrequent trips. Mechanically, while this suggests less wear on the engine and drivetrain components, it often correlates with the types of issues seen in the MOT history, such as accelerated corrosion on brake pipes and suspension components which can occur when vehicles are not regularly driven to clear moisture or prevent surface oxidation from progressing. Prospective buyers should pay close attention to the suspension and braking systems during a physical inspection and test drive. The 2024 test flagged a fractured nearside rear coil spring and corrosion on the offside rear spring, alongside worn front suspension arm bushes. On a test drive, listen for any knocking, clunking, or creaking sounds when traversing uneven surfaces or speed bumps, which could indicate that the suspension bushes or springs have not been fully rectified or are deteriorating again. Additionally, check for any steering pull or instability when braking, as the history of heavily corroded brake pipes and brake fluid visibility issues suggests the hydraulic integrity of the braking system is a primary area of concern. Given the previous major failures involving brake pipe corrosion across all four corners, a thorough visual inspection of the underbody is essential. Look for signs of weeping around brake unions or any evidence of recent repairs to the lines. Any sensation of a spongy or inconsistent brake pedal during operation should be treated as a high priority, as it may relate to the previous dangerous failure regarding brake fluid levels. The presence of a full body under tray, noted as an advisory in 2023, may have obscured the view of the subframe and brake lines during previous tests, so a dedicated inspection of the chassis for structural corrosion is advised.
