2020 Mercedes-Benz S-Class 2.9L Diesel · BA04 UER

The most recent MOT on 30 October 2025 recorded a pass at 100,744 miles, indicating that the vehicle met the statutory safety and emissions standards at that date. The preceding failure on 29 October 2025 recorded no defects, suggesting an administrative issue rather than a mechanical shortfall, and the uninterrupted passes in 2024 and 2023 reinforce a stable maintenance pattern. Mileage has risen sharply over the past three years. From 67,366 miles on 17 November 2023 the odometer increased to 83,351 miles by 11 November 2024, a gain of 15,985 miles in twelve months. The next interval saw a further rise to 100,744 miles on 30 October 2025, adding 17,393 miles in just under eleven months. At roughly 16,800 miles per year, the car has been driven well above average for a 2020 S‑Class, implying accelerated wear on consumables and load‑bearing components. A prospective buyer should examine tyre tread depth and uniformity, as high mileage often coincides with uneven wear. Inspect brake discs and pads for glazing or excessive scoring, and verify that calipers operate without binding. Check suspension bushings, coil springs, and any audible clunks that could signal fatigue from the mileage load. A visual survey for corrosion on chassis rails, wheel arches, and exhaust manifolds is prudent, as well as a functional test of the emission control system to confirm compliance beyond the MOT record. These inspections will corroborate the clean MOT history and reveal any latent wear that high mileage may have introduced.
