2007 Mercedes-Benz S-Class 3.0L Diesel · DJ03 WEN

The vehicle shows a history of reactive maintenance, where faults are often addressed only after failing an initial MOT test. In the most recent test in November 2025 at 149,889 miles, the car passed despite advisories for slight play in both front wheel bearings. This followed a failure just one day prior where the offside front tyre was rejected for exposed cords and the nearside front tyre was at the legal limit. The recurring presence of wheel bearing play and brake component wear suggests that while the vehicle is kept moving, components are replaced as they fail rather than following a preventative service schedule. At 149,889 miles over 19 years, the car has averaged roughly 7,900 miles per year, which is consistent with typical usage for a luxury S-Class. However, the record reveals a persistent issue with the braking system's integrity. Between 2021 and 2024, multiple brake pipes and hoses were flagged for corrosion and deterioration across all corners. The tester noted the front pipes were corroded in 2023, which expanded to all four hoses by 2024, indicating an ongoing environment of significant rust under the underbody. The suspension also shows signs of age, with the offside front lower suspension arm bush being noted as excessively worn in 2024 and merely worn in the previous year, suggesting a gradual failure or incomplete fix. Structural concerns appear in the fuel tank, noted for slight corrosion in 2021, which remains a long-term risk for a vehicle of this age. A buyer should specifically inspect the front suspension arm bushings and the condition of the brake fluid lines, as the history indicates these are areas prone to recurring degradation on this specific chassis.
