2017 Mercedes-Benz S-Class 3.0L Diesel · DN17 OVP

The vehicle is currently roadworthy but the maintenance trend shows a consistent pattern of reactive rather than proactive upkeep. The latest test in August 2025 at 112,614 miles indicates a pass despite advisories for rear tyres being near the legal limit and showing uneven wear. This follows a multi-year trend where consumable components are ignored or only addressed once they approach failure thresholds, rather than being replaced during scheduled intervals. The mileage profile reveals a significant acceleration in use over the last four years. While the car sat relatively low at 43,096 miles in April 2021, it covered nearly 70,000 miles by August 2025. The jump of over 20,000 miles between the 2023 and 2024 tests highlights high-intensity usage for a luxury S-Class. This rapid accumulation puts substantial strain on the complex air suspension systems and drivetrain, which is consistent with the frequent reports of wear and tear recorded in the history. A buyer must conduct a thorough inspection of the front suspension, as the 2023 test flagged play in both front arm ball joints at 83,861 miles. Given the high mileage since then, these components and the associated bushings are likely nearing the end of their life. The recurring advisories for uneven tyre wear across multiple years (2022, 2023, 2024, and 2025) suggest alignment issues or worn suspension geometry remains unaddressed. The braking system also requires attention as the tester flagged thin front pads in 2024 and thin rear pads in 2023. You should verify the current thickness of all pads and check for disc scoring or thinning caused by the high mileage. The presence of engine covers and under trays in recent tests is a positive sign for protection, but the overall history suggests a vehicle that has seen deferred preventative maintenance.
