2006 Mercedes C 2.1L Diesel · BU06 KZL

The vehicle is currently roadworthy, but the maintenance history shows a worsening trend regarding suspension and bearing components. While it passed its latest test in November 2025 at 70,073 miles, this followed a failure just one day prior due to multiple mechanical defects. The transition from a failure to a pass suggests reactive repairs were made, yet the persistence of issues with the anti-roll bar bushes and wheel bearings indicates that these components are reaching the end of their functional life and require ongoing attention despite the low mileage. The mileage profile is exceptionally low for a twenty-year-old Mercedes, averaging approximately 3,500 miles per year. There is a significant gap of 2,653 miles between the September 2024 test and the November 2025 test, suggesting the car is used sparingly for short journeys or has sat stationary for extended periods. This low usage often preserves the engine and interior, but it frequently leads to the degradation of rubber components and seals, which is evidenced by the corrosion on the rear coil springs and the perished dust covers on the front anti-roll bar ball joints. A buyer must conduct a thorough physical inspection of the front suspension geometry. The record has repeatedly flagged play in the offside front wheel bearing and wear on the anti-roll bar bushes across 2023 and 2025. Furthermore, the corrosion on both rear coil springs is a serious concern for structural integrity, as rust can lead to sudden spring failure and an immediate fail in the next test. The noisy nearside rear wheel bearing noted in late 2025 also should be checked for clearance to ensure the wear has not progressed since the last advisory.
