2010 Mercedes-Benz S-Class 3.0L Diesel · DIA 106

The vehicle is currently roadworthy, but the maintenance history reveals a pattern of reactive rather than preventative care. While the most recent test in October 2025 at 118,734 miles identified a corroded brake pipe covered in grease, the car passed despite this defect. This recurring issue was first noted in November 2022. The fact that the vehicle passed its subsequent test in November 2024 after a significant failure for brake-related issues suggests that components are only addressed once they reach a point of failure. At 118,734 miles over 16 years, the car has averaged approximately 7,400 miles per year, which is consistent with low-to-moderate annual use. The usage pattern shows steady intervals between tests, with roughly 3,500 miles covered between November 2024 and October 2025. This low mileage suggests the vehicle has not been subjected to heavy motorway stress, but it often correlates with the degradation of rubber-based components and the corrosion of metal lines over time, as seen in the record. A buyer must conduct a thorough inspection of the braking system and chassis lines. The failure in November 2024 at 115,217 miles highlighted significantly worn discs and fluctuating service brakes across all axles, indicating a major overhaul was likely performed then. The presence of grease on corroded brake pipes mentioned in the latest report is a particular concern, as it often indicates an attempt to mask surface rust from the tester. You should inspect the entire length of the brake lines for further thinning or structural decay. The suspension and wheels also require close attention. The 2022 record flagged play in the front wheel bearings, and consistent advisories for all four tyres being worn to the legal limit on the edges in 2023 suggest alignment issues or neglect of basic consumable maintenance. Given the age of this S-Class, check for the integrity of the control arm bushings and air suspension components, as these are common points of failure on this model that are not always captured in a standard MOT until they become a safety risk.
