2009 Mercedes-Benz ML 3.0L Diesel · KS09 WWX

The vehicle remains roadworthy but the maintenance history reveals a worsening trend of deferred mechanical repairs and ongoing corrosion. While the car passed its most recent test in December 2025 at 142,235 miles, it carried a high volume of advisories that have persisted or escalated over several years. The persistence of corroded brake pipes and leaking shock absorbers suggests that the owner is addressing only the minimum requirements to pass the MOT rather than engaging in proactive preventative maintenance. At 17 years old, the recorded mileage of 142,235 miles represents a consistent usage pattern of approximately 8,300 miles per year. The data shows a steady accumulation, with roughly 3,400 miles driven between the December 2024 and December 2025 tests, and approximately 5,300 miles between December 2023 and 2024. This relatively low annual mileage has not prevented age-related degradation of rubber components and metalwork, which are the primary concerns identified in the record. A buyer must prioritise a thorough inspection of the braking system and suspension geometry. The tester flagged corroded front-to-rear metal brake pipes in 2022, 2023, 2024, and 2025, indicating a progressive rust issue that will eventually lead to a pipe failure. The nearside rear shock absorber has progressed from a light misting in 2023 to a confirmed leak by 2025. Furthermore, the appearance of slight play in the steering rack during the most recent test indicates internal wear in the steering assembly that may soon require a costly replacement. Specific attention should also be paid to the parking brake and drivetrain components. The nearside rear parking brake cable casing has been splitting since 2023, and handbrake performance has been noted as low for three consecutive years. The history of weeping grease from the offside front driveshaft boot, noted in 2022 and 2023, suggests the joint is nearing failure. Given the inner-edge wear on the offside front tyre noted in 2025, the vehicle likely suffers from alignment issues or worn suspension bushes that require professional attention.
