2012 Mercedes-Benz C 3.0L Diesel · LA12 UNR

The vehicle is currently roadworthy but the maintenance trend shows signs of reactive rather than proactive care. While it passed its most recent test on 20 December 2025 at 104,857 miles, it failed earlier that same day due to an inoperative engine management light and a persistent oil leak. The recurring nature of the oil leak across multiple tests in 2025 indicates an ongoing issue that the previous owner has neglected to fully rectify despite repeated MOT flags. The mileage pattern is consistent with a 14-year-old vehicle, averaging approximately 7,500 miles per year. There is a significant gap in records between the December 2023 test at 78,470 miles and the January 2025 test at 95,701 miles, during which the car covered over 17,000 miles in just fourteen months. This suggests a period of much intensive use which likely contributed to the accelerated wear of rubber components and suspension elements seen in the subsequent 2025 failures. A buyer must personally inspect the front suspension and alignment geometry. The record shows uneven wear on the inner edge of the offside front tyre in December 2025 and a previous failure regarding the anti-roll bar ball joint dust cover in January 2025. These faults, combined with the noted play in the offside front wheel bearing from 2023, suggest the front-end components are reaching the end of their functional life. The engine system should be scanned with a diagnostic tool to ensure the malfunction light failure was properly cleared and does not mask a deeper sensor or emissions fault.
