2016 Mercedes-Benz S-Class 3.0L Diesel · P5 KSF

The vehicle remains roadworthy, but the maintenance trend shows a recent decline in preventative component care. While the most recent test in February 2026 at 103,245 miles passed, the tester identified significant pitting and scoring on both front and rear brake discs. This mirrors the exact findings from the February 2025 test at 97,956 miles, indicating that the braking system is experiencing surface corrosion or accelerated wear despite the previous advisory. The mileage pattern is consistent with a ten-year-old luxury saloon, averaging approximately 10,300 miles per annum. Between February 2022 and February 2024, the car covered roughly 12,000 miles with no recorded defects, suggesting a period of good upkeep. However, the 5,300 miles driven between early 2025 and 2026 coincide with the appearance of mechanical wear-related faults, suggesting that the vehicle is now entering a stage that requires more frequent inspection of high-wear items. A buyer must prioritize a thorough physical inspection of the braking assembly. The recurring reports of pitting and scoring across two consecutive years suggest the owner has neglected to replace the discs, which can lead to reduced braking performance and caliper damage if left untreated. You should also check the offside front tyre to ensure the cut noted in 2025 not progressed into structural failure. Given the age and mileage of this S-Class, verifying the condition of the air suspension components and bushings is essential, as the MOT record does not account for these systems until they fail a functional test.
