2018 Mercedes-Benz S-Class 2.9L Diesel · LM68 ACU

The vehicle maintains a stable roadworthiness status with a clean MOT history. The most recent test on 16 April 2025 at 127,416 miles resulted in a pass with no defects or advisories recorded. This follows a consistent pattern of clean passes dating back to May 2023, suggesting the car has been kept in a condition that meets minimum legal safety standards without recurring failures. The mileage is high for an eight year old vehicle, averaging nearly 16,000 miles per year. The record shows rapid accumulation in the latter stages of its history. Between 20 May 2023 and 16 April 2025, the odometer climbed from 110,390 to 127,416 miles. This indicates the car has likely spent significant time on motorways, which typically places less stress on the engine and gearbox than urban stop-start driving, though it accelerates wear on other components. Despite the clean MOT record, the high mileage necessitates a focused physical inspection of long-term wear items. The absence of advisories is unusual for a vehicle of this age and mileage, so a buyer should manually verify the condition of the suspension bushes and coil springs. Air suspension components on the S-Class are prone to degradation over time and high mileage, regardless of whether they trigger an MOT failure. Check the brake discs and pads for thinning and inspect the tyres for uneven wear, which could signal alignment issues. While the DVSA records show no structural corrosion or exhaust emissions failures, the high mileage suggests the drivetrain and transmission fluids should be checked against service records to ensure they have been changed according to the manufacturer's intervals.
