2017 Mercedes-Benz S-Class 3.0L Diesel · AF17 NZC

Recurring brake component wear and previous tyre tread depth failures define the mechanical profile of this vehicle, though the most recent test on 09 January 2026 shows a clean pass with no defects. The history reveals a pattern of brake disc deterioration, specifically noted as pitted or scored on both the nearside and offside rear discs in January 2024, following earlier advisories for front and rear discs in 2022. While the 2023 failure for dangerously low tyre tread depth was resolved, the intermittent advisories regarding braking surfaces and suspension ball joint play suggest a history of wear on consumable components and steering linkages. The recorded mileage of 109,138 miles over approximately nine years indicates an average annual usage of roughly 12,126 miles, which is relatively high for a vehicle of this age and class. This level of accumulation suggests consistent motorway or long-distance driving, which can impact the longevity of complex suspension systems and drivetrain components. While the mileage is not extreme, the cumulative distance increases the likelihood of wear on the various bushings, ball joints, and braking systems that have been previously flagged in the MOT record. Prospective buyers should pay close attention to the braking system during a test drive, specifically looking for any pulsation or judder through the brake pedal when applying pressure at speed, which can indicate uneven disc wear or warping. Given the previous advisories regarding pitted and scored rear brake discs, it is essential to inspect the condition of the discs and pads for excessive scoring or uneven thickness. Any unusual squealing or grinding noises during low-speed braking should be treated as a sign of further component degradation. The 2022 advisory regarding slight play in the nearside and offside front suspension arm ball joints warrants a thorough inspection of the front-end steering and suspension integrity. On a test drive, listen for any rhythmic knocking or clunking sounds when driving over uneven road surfaces or speed bumps, and check for any wandering or pulling sensation in the steering wheel that might suggest worn linkages. Ensuring that the suspension components are tight and free of excessive movement is critical given the documented history of play in these specific areas.
