2011 Mercedes-Benz C 2.1L Diesel · CU11 GGV

The vehicle remains roadworthy but the maintenance trend shows a pattern of reactive repairs rather than proactive care. While the most recent test in September 2025 at 84,920 miles passed, it revealed several wear-related issues including thin rear brake pads and corroded rear brake pipes. The presence of grease on these corroded pipes suggests a previous attempt to mask corrosion or a past fluid leak, which is a common indicator of deferred maintenance regarding the integrity of the braking hydraulic lines. At 84,920 miles, this 15-year-old Mercedes has low annual mileage, averaging approximately 5,600 miles per year. The data shows consistent usage with roughly 5,000 to 6,000 miles driven between annual tests from 2022 and 2025. However, there was a significant failure in September 2023 at 74,461 miles due to an ABS fault and critical front brake pad thickness, indicating that the vehicle occasionally operated with neglected components until a failure forced intervention. A buyer must conduct a close inspection of the braking system and suspension components. The record notes recurring issues with rear brake pads across 2023 and 2025, alongside long-term corrosion on the brake pipes. The 2022 advisory regarding wheel bearing play on both front wheels requires physical re-verification to ensure these were replaced or if the wear has progressed. Additionally, the persistent oil leak noted since 2022 warrants a thorough check of the engine seals and sump to determine if it is a minor seep or a more significant gasket failure that could lead to oil starvation.
