2016 Mercedes-Benz C 2.1L Diesel · X 444

The vehicle remains roadworthy, having passed its most recent MOT in May 2026 at 87,286 miles. However, the maintenance trend shows a developing issue regarding the braking system. While the 2024 test showed no defects, both the 2025 and 2026 tests flagged the front service brakes for fluctuating, though not exceeding limits. This suggests a persistent mechanical inconsistency with the front discs or calipers that has not been fully rectified by the previous owner. The mileage pattern is consistent with a ten-year-old vehicle, averaging approximately 8,700 miles per annum. There is a notable gap in records between May 2019 and November 2020, where the car covered nearly 20,000 miles in eighteen months. Since 2021, the usage has become more regular, with roughly 6,000 to 7,000 miles added each year. This steady usage is generally positive for mechanical components compared to long periods of sitting, which can lead to degradation of rubber-based parts. A buyer must inspect the front brake assembly specifically to determine if the fluctuation is caused by warped discs or sticking pistons. The 2023 failure at 84,025 miles revealed thin rear brake pads and an inoperative engine malfunction indicator light, indicating a period where basic maintenance was neglected. You should also check for uneven tyre wear, as the records from 2019 and 2020 highlighted tyres worn on the edges, which often points to alignment issues or worn suspension bushings. The electronic system should be verified to ensure the MIL fault reported in 2023 was properly cleared and not merely masked.
