2020 Mercedes-Benz S 350 L Grand ED Executive D A 2.9L Diesel · WN20 AAU

The vehicle currently holds a valid MOT following a pass on 19 May 2026 at 272,846 miles. While the most recent result shows no defects, the maintenance trend appears reactive rather than preventative. The car failed just one week prior on 12 May 2026 at 272,144 miles due to a structural bulge in the nearside front tyre. This follows a pattern of recurring tyre issues and suspension component failures seen in previous years. The mileage accumulation is exceptionally high for a vehicle of this age, averaging approximately 45,000 miles per year. Between May 2025 and May 2026, the vehicle covered nearly 48,000 miles, and between May 2024 and May 2025, it covered roughly 51,000 miles. This intensive usage suggests constant long-distance motorway driving, which places significant stress on the drivetrain and suspension systems. The rapid increase in mileage between tests confirms the vehicle is in heavy, continuous use. A buyer must conduct a thorough physical inspection of the suspension and steering components. The May 2025 failure at 224,543 miles identified an excessively worn nearside front lower suspension arm ball joint, and the repeated advisories regarding inner tyre wear suggest potential alignment issues or worn suspension bushes. The May 2024 record noted worn brake discs across all four corners, indicating that the braking system is subject to heavy wear and may require imminent replacement of discs and pads. Structural integrity should also be verified. The May 2023 failure at 123,599 miles flagged a welding defect on the nearside rear road wheel. While the vehicle has passed since then, the high mileage and previous structural advisory necessitate a close look at the chassis and wheel arches for signs of corrosion or previous repair work. Given the high mileage, an inspection of the engine's service history is essential to ensure the mechanical components have been maintained alongside these MOT requirements.
