2013 Mercedes-Benz C 2.1L Diesel · OY13 YJG

The vehicle is currently roadworthy, but the maintenance history reveals a worsening trend regarding mechanical component integrity. While it passed its most recent test in December 2025 at 149,351 miles, the preceding failure just eight days prior highlights significant neglect. The December 2025 failure was due to high exhaust emissions and multiple failures across the front suspension, including worn ball joints and bushes. The persistent presence of an oil leak across every recorded test since 2023 indicates a chronic issue that the owners have monitored rather than rectified. The mileage pattern is consistent with a 13-year-old vehicle, averaging approximately 11,500 miles per year. Between December 2023 and December 2024, the car covered 7,374 miles, followed by nearly 19,000 miles in the year leading up to the December 2025 tests. This usage suggests regular road use, which explains the progressive wear on rubber-based suspension components, but the recent spike in mileage may have accelerated the wear-related failures. A buyer must inspect the front-end suspension assembly closely, as the record shows a history of failing ball joints and worn arm bushes on both sides. The 2024 advisory for slight play in both front wheel bearings should be verified to ensure these have been replaced, as they are prone to failure. Furthermore, the 2023 report of corrosion on the rear sub-frame requires a thorough physical inspection to ensure structural rust has not progressed beyond being not seriously weakened, as this is a common failure point for this model. The recurring exhaust emissions failure in late 2025 suggests potential issues with the fuel system or turbocharger that require diagnostic attention. Given the persistent oil leak and the corroded brake pipes noted in 2023, the underbody should be checked for fluid ingress and advanced degradation of lines. The history suggests a reactive approach to maintenance, where faults are only addressed when they threaten an MOT rather than through proactive preventative care.
