2008 Mercedes-Benz R-Class 3.0L Diesel · X15 HEX

The vehicle's roadworthiness status is currently poor, with a significant worsening trend in mechanical condition evidenced by the February 2025 failure at 146,845 miles. While the car achieved a clean pass in March 2024 at 144,373 miles, the subsequent test revealed an extensive list of critical failures. This recent failure includes an ABS fault, defective parking brake, and a worn nearside front outer drive shaft joint with a split CV boot. The sheer volume of defects in the most recent test suggests a period of neglected maintenance or a rapid deterioration of components that were previously stable. The mileage history shows a consistent usage pattern of approximately 8,000 miles per year, which is typical for a vehicle of this age. Between the March 2024 pass and the February 2025 failure, the vehicle covered roughly 2,500 miles. This relatively low interval between tests, combined with the sudden influx of major mechanical issues, indicates that the vehicle may have been driven without addressing accumulating wear. The progression from minor oil leaks in 2020 and 2023 to more complex failures in 2025 suggests that maintenance has been reactive rather than preventative. A prospective buyer must conduct a thorough physical inspection of the braking and suspension systems. The record shows a chronic issue with rear brake pipe corrosion dating back to 2020, which resurfaced in the 2025 test. There is also a recurring pattern of corroded rear coil springs and worn shock absorber bushes. The 2025 report specifically flagged a rough nearside front wheel bearing and distorted road wheels, which necessitates a close examination of the entire front-end hub and suspension geometry. Beyond the chassis, the electrical and drivetrain components require scrutiny. The recent ABS warning lamp and parking brake defects, alongside previous issues with headlamp aim and intensity, suggest potential electrical or sensor failures. The presence of an ongoing oil leak, noted in multiple tests between 2020 and 2025, means the engine and gearbox seals should be checked for severity. Finally, the repeated failures regarding drive shaft boots and joints imply that the drivetrain may require significant investment to ensure long-term reliability.
