2014 Mercedes-Benz S-Class 3.0L Diesel · TE02 AAA

The vehicle is currently roadworthy following a clean pass in September 2025 at 68,378 miles, yet the recent maintenance trend shows a concerning lapse into mechanical instability. A failure just three weeks prior to that test at 68,156 miles revealed multiple critical defects including an excessively worn offside front suspension arm ball joint, a structurally failed nearside tyre, and an inoperative engine management light. While these faults were rectified to secure the subsequent pass, the density of these distinct mechanical failures suggests a reactive maintenance approach rather than proactive preventative care. The mileage profile is notably low for a twelve-year-old S-Class, averaging approximately 5,700 miles per year. The data shows consistent usage over the years, moving from 55,092 miles in late 2022 to 68,378 miles by late 2025. However, the low mileage often correlates with age-related degradation of rubber components such as suspension bushings and seals, which is evidenced by the steering rack inner joint play flagged back in the October 2022 test despite the relatively low distance covered. A prospective buyer must conduct a thorough physical inspection of the front suspension geometry to ensure the recently replaced ball joint and arm have not caused secondary wear on related components. The history of steering rack play necessitates a close check for any remaining vibration or loosen in the steering wheel during a test drive. Furthermore, given the engine management light failure in the September 2025 test, a professional diagnostic scan is essential to ensure no hidden fault codes remain in the engine computer that were simply cleared to pass the MOT.
