2009 Mercedes-Benz R-Class 3.0L Diesel · P24 MRA

The vehicle remains roadworthy but the maintenance history shows a concerning trend of deferred reactive repairs rather than preventative care. The most recent test in September 2024 at 149,882 miles identified multiple advisories across the suspension, braking, and tyre-related systems. While the car passed, the accumulation of faults including four worn tyres and thinning rear brake pads suggests that components are only being addressed once they reach the point of legal failure or near-failure thresholds. The mileage pattern is consistent with a 17-year-old vehicle, averaging approximately 8,800 miles per year to reach the current quarter-million-mile total. However, there is a significant three-year data gap between the January 2020 and July 2023 tests, during which the vehicle covered only 3,745 miles. This period of low use likely explains the perishing and cracking noted on the outer front tyres in the 2023 report, as rubber compounds degrade over time and lack of movement regardless of tread depth. A buyer must conduct a thorough inspection of the front shock absorbers, which have shown light misting of oil in both 2023 and 2024. This indicates a seal failure that will eventually worsen. The rear sub-frame also requires close scrutiny as the 2024 tester flagged corrosion; although not yet structurally weakened, surface rust on a vehicle of this age can accelerate rapidly if not treated. The recurring reports of a front oil leak and the pitted condition of both front and rear brake discs indicate a history of component-level neglect. The 2024 advisory for all four tyres being worn close to the limit and on the edges suggests potential alignment issues or incorrect pressure management. Before purchasing, budget for a full set of tyres, a complete brake overhaul, and a professional investigation into the oil leak to ensure it is not a critical engine seal.
