2008 Mercedes-Benz S-Class 3.2L Diesel · SN57 CTM

The vehicle's roadworthiness status shows a recent period of instability following a significant decline in mechanical condition. While the most recent test on 24 July 2024 at 78,624 miles resulted in a pass, it followed a failure just one day prior due to a fractured and distorted offside front road wheel. The maintenance trend appears inconsistent, characterized by a sharp spike in suspension and braking component failures between August 2023 and July 2024, suggesting that previous neglect or long periods of inactivity may have led to a sudden accumulation of wear. The mileage profile indicates a very low-use vehicle, averaging approximately 4,368 miles per year over its 18-year lifespan. There is a notable jump in usage between September 2022 and August 2023, where the mileage increased from 62,037 to over 71,000 miles in less than a year. This period of higher activity coincided with a series of heavy MOT failures. The current recorded mileage of 78,624 is low for a vehicle of this age, but the data suggests that the low annual usage may have contributed to the degradation of rubber components and the onset of corrosion. A prospective buyer must conduct a thorough physical inspection of the suspension and steering systems. The MOT history reveals a recurring pattern of issues with sub-frame pins, bushes, and Macpherson strut ball joints, particularly during the multiple failures in August 2023. The tester also flagged several instances of wheel bearing play and fractured wheels. Given the history of brake pipe corrosion and damage reported in 2019, 2020, and 2023, the integrity of the entire braking system, including lines and connections, requires close scrutiny to ensure no further degradation is present. The presence of an engine management light in the August 2023 tests indicates potential underlying electronic or sensor issues that should be diagnosed via an OBD scanner. While the vehicle passed its most recent test, the sheer volume of components flagged for excessive wear in the preceding year suggests that the car has recently undergone significant remedial work or is nearing a phase where further component replacements will be necessary. Focus should be placed on the condition of the sub-frame and the recent replacement of the offside front wheel to ensure the repairs were comprehensive.
