2016 Mercedes-Benz S-Class 3.0L Diesel · RGB 3

The most recent MOT test on 12 December 2025 resulted in a pass, though it introduced advisories regarding perished air suspension gaitors on both the nearside and offside front. Looking at the historical trend, the vehicle has maintained a consistent pass record, but there is a noticeable emergence of age-related advisories over the last three years. While the vehicle remains compliant, the progression from brake disc wear in 2023 to tyre wear in 2024 and now air suspension degradation suggests the car is entering a period where more significant maintenance of consumable and rubber components will be required to maintain its premium ride quality. With 81,433 miles recorded over a ten-year period, the vehicle has averaged approximately 8,143 miles per year. This represents typical, moderate usage for a luxury saloon of this class. This mileage profile is generally positive as it suggests the vehicle has been used regularly enough to prevent excessive component seizure or fluid degradation from long periods of standing, yet it has not been subjected to the heavy mechanical strain associated with high-mileage commercial or fleet use. However, at this stage of its life, the mileage is sufficient to necessitate a thorough inspection of all wear-sensitive items, particularly those involving rubber and hydraulic systems. Prospective buyers should pay particular attention to the air suspension system, given the recent advisories regarding the perished gaitors on the front units. These gaitors protect the air bellows from environmental damage and debris; if they fail, it can lead to air leaks or the eventual failure of the suspension module. During your test drive, listen closely for any audible hissing sounds when the vehicle adjusts its height and observe if the car settles unevenly when parked. You should also check for any significant bouncing or lack of damping over undulations, which could indicate the air bags or struts are losing pressure or failing to regulate. Furthermore, the previous advisories regarding rear tyre wear and front brake disc wear should be verified against recent service records or physical inspection. Examine the current tread depth and check for uneven wear on the tyre edges, which could point to underlying suspension bush wear or incorrect wheel alignment. Regarding the brakes, inspect the front discs for heavy scoring or lip formation and feel for any shudder or pulsation through the brake pedal during deceleration. Given the age and the specific advisories noted, it is essential to confirm that these components have been replaced or that the vehicle has a comprehensive service history to support its ongoing mechanical integrity.
