2017 Mercedes-Benz C 2.1L Diesel · XM04 RAD

A recurring pattern of suspension component wear and tyre degradation defines the mechanical history of this Mercedes-Benz C-Class, despite a clean result in its latest test on 19 January 2026. The record shows a progression from a slight play in the offside front lower suspension arm ball joint noted as an advisory in January 2024, to a major failure of the nearside front lower suspension arm ball joint in January 2025. While the subsequent retest in 2025 and the most recent test in 2026 show no defects, the history indicates that suspension linkages are a specific area of wear for this vehicle. The vehicle has covered 61,010 miles over its nine-year lifespan, representing an average annual accumulation of approximately 6,779 miles. This usage profile is consistent with typical light-to-moderate driving patterns for a vehicle of this age. From a mechanical standpoint, this level of mileage suggests that components such as suspension bushes, ball joints, and tyres are subject to standard age-related degradation rather than high-intensity wear associated with long-distance motorway commuting. Prospective buyers should pay close attention to the steering and suspension response during a test drive to ensure the previous ball joint failures have been fully rectified. Listen for any knocking, clunking, or creaking noises when navigating uneven road surfaces or turning the steering wheel at low speeds, as these can indicate residual play in the suspension arms or worn bushes. Additionally, check for any pulling to one side or steering instability, which may stem from uneven wear in the front-end geometry. Given the advisories regarding nearside and offside rear tyres being worn close to the legal limit in 2024, a thorough inspection of the current tread depth and evenness of wear is necessary. Look specifically for uneven wear on the inner or outer edges of the rear tyres, which could indicate alignment issues or camber faults. While the most recent records show no current defects, verifying the condition of the tyre sidewalls and ensuring the tread depth is well above the legal minimum is a vital step in confirming the vehicle's current roadworthiness.
