2015 Mercedes-Benz S-Class 3.0L Diesel · RAB 66T

The 2015 Mercedes-Benz S-Class passed its most recent MOT on 9 December 2025 at 72,709 miles with advisories related to nearside rear brake pads, both rear brake discs, and inner rear tyres. These items indicate wear rather than immediate failure but suggest that the braking system and tyres are approaching replacement thresholds. The presence of similar advisories in prior years, particularly for brake discs and oil leaks, shows a consistent pattern rather than a worsening trend, though the latest test reveals more specific wear items than previous years. The vehicle remains roadworthy but will require close attention to the braking system and tyre condition in the near term. The car has accumulated 72,709 miles over approximately 11 years, averaging around 6,610 miles per year. This is a typical usage rate for a luxury saloon of this age. The recorded mileage increased steadily between tests, with a 2,153-mile gain between the 2024 and 2025 tests over a 12-month period. There are no significant mileage jumps or gaps in the MOT history, which spans from November 2021 to December 2025. The consistent annual testing and mileage progression suggest regular use without prolonged periods of inactivity that might otherwise affect mechanical reliability. Advisories related to oil leaks have appeared in every MOT since November 2021. While not excessive, these leaks may indicate ongoing issues with seals or gaskets that could worsen over time. The repeated mention of engine covers and undertrays obscuring components raises concerns about accessibility for inspection and maintenance. A prospective buyer should inspect for signs of hidden corrosion or mechanical wear underneath these covers. The recurring brake disc wear and recent tyre advisories suggest the need for a thorough inspection of the rear braking system, suspension bushes, and remaining tyre tread depth. Given the vehicle’s age and mileage, structural integrity and suspension components should also be carefully checked in person.
