2013 Mercedes-Benz C 6.2L Petrol · AS11 EAR

This vehicle presents a pattern of chronic component degradation rather than sudden mechanical failure, with the most recent MOT test on 28 May 2026 recording a failure to pass the brake disc wear criteria despite an overall pass. The advisory notes inner brake discs that are worn, pitted, or scored, indicating significant friction material loss or surface damage that compromises braking efficiency and surface finish. Over the preceding eight years, the service history reveals a progressive decline in both braking and drivetrain components, starting with corroded front brake discs in 2018 and evolving into rear prop shaft coupling deterioration by 2020, suggesting a vehicle that has experienced consistent, albeit low, usage that has nonetheless accelerated the wear of these specific assemblies. With a recorded mileage of 31,270 miles over approximately thirteen years, the annual accumulation rate of roughly 2,405 miles indicates very light usage, which typically preserves mechanical components but can paradoxically accelerate certain forms of wear such as corrosion and fluid degradation. The consistent passing of MOT tests over the last five years without major failures suggests the vehicle has not been subjected to harsh driving conditions or high stress, yet the specific advisories on brake discs and prop shaft couplings point to underlying issues that have persisted despite low mileage. This usage profile implies the vehicle has likely spent significant periods stationary, potentially allowing moisture ingress into the brake system and leading to the pitting and scoring observed on the inner brake discs, while the rear prop shaft coupling deterioration points to a slow, progressive failure of the flexible joint rather than high-speed wear. Prospective buyers must scrutinise the braking system thoroughly, specifically checking the inner faces of the front brake discs for uneven wear patterns or deep scoring that could cause brake judder during deceleration. The advisory regarding inner brake disc wear indicates that the friction material may be approaching the minimum legal thickness, necessitating an immediate inspection to determine if replacement is required before the next MOT test. Furthermore, the recurring advisories on prop shaft couplings from 2019 and 2020 suggest the flexible joint is losing its ability to absorb drivetrain vibration, which may manifest as a noticeable vibration or rumble through the vehicle floor or steering wheel, particularly during acceleration or when changing gears.
