2014 Mercedes-Benz S-Class 3.0L Diesel · AL05 AFC

The vehicle presents a stable but deteriorating maintenance profile, with the most recent test in January 2026 showing an increase in mechanical advisories. While the car passed its latest inspection at 140,947 miles, the tester flagged pitting and scoring on both front and rear brake discs, alongside play in both front lower suspension arm ball joints. This indicates that while the vehicle remains roadworthy, wear on consumable and steering components is progressing. The mileage accumulation is consistent with a typical long-distance use pattern for a 12-year-old vehicle, averaging approximately 11,700 miles per year. The record shows steady progression from 36,187 miles in April 2017 to the current 140,947 miles. There are no significant gaps in testing frequency, although the jump between the June 2018 test and the January 2019 test suggests a slightly longer interval between inspections. A buyer should prioritise a physical inspection of the front suspension system. The ball joints have been flagged for play in two consecutive tests, specifically in January 2025 and again in January 2026, suggesting that previous repairs or replacements have not fully resolved the issue or that the components are wearing rapidly. This recurring fault points to a need for thorough checking of the front wishbones and associated bushings to ensure steering precision and stability. The braking system requires close attention. The January 2024 test noted thin pads across all four corners, and by January 2026, the discs themselves showed signs of surface degradation and scoring. Given the age and mileage, a buyer should verify the thickness of the remaining pads and the condition of the rotors to avoid immediate replacement costs. Previous issues with tyre tread depth and low headlamp aim suggest a history of minor oversight regarding basic upkeep, though these appear to be resolved.
