2012 Mercedes-Benz C 2.1L Diesel · FY12 AEU

The vehicle shows a history of recurring mechanical wear, specifically concentrated in the braking system and suspension components. The most recent test in February 2025 at 168,728 miles resulted in a failure due to seriously weakened front and rear brake discs, along with excessively worn front anti-roll bar ball joints. While it passed the following day, the tester noted a corroded rear brake pipe and corrosion on the subframe mounting area. This pattern of brake pipe corrosion is persistent, having been flagged as far as 2024 and 2023, suggesting an ongoing issue with environmental protection or material degradation in the fluid lines. At 168,728 miles over 14 years, this Mercedes has covered an average of approximately 12,000 miles per year. There is a significant jump in usage between September 2021 and February 2025, where the vehicle covered over 60,000 miles in under four years. This high rate of travel explains the accelerated degradation of consumables and suspension parts. The record indicates frequent failures of ball joints, suspension arms, and coil springs, which are typical for high-mileage German subjected subjected to stress. Structural integrity remains a point of long-term monitoring. The subframe mounting area was noted for corrosion in both 2024 and 2025; although the tester did not consider it excessive at that time, the recurring presence of rust on a load-bearing member requires a close physical inspection to ensure it has not progressed toward structural failure. The repeated failure of ball joints across a 10-year period suggests that previous owners only replaced components once they reached a point of total failure rather than performing preventative maintenance.
