2015 Mercedes-Benz C 2.1L Diesel · ALZ 1

High annual mileage and recent brake wear are the primary mechanical considerations for this vehicle, which most recently achieved a clean pass on 15 May 2026. While the testing history shows a period of clean passes between 2021 and 2023, the 2025 inspection introduced advisories regarding thinning rear brake pads and worn brake discs. Although these specific issues do not appear to have resulted in a failure by the 2026 test, the progression from worn components to a clean certificate suggests a recent replacement or intervention regarding the braking system. The vehicle has covered 149,144 miles over its eleven-year lifespan, representing an average annual accumulation of approximately 13,559 miles. This usage pattern is higher than the UK average for a vehicle of this age, indicating consistent long-distance or high-frequency road use rather than short, infrequent trips. Mechanically, this sustained mileage increases the likelihood of accelerated wear on consumable items and structural components, particularly within the suspension system, drivetrain, and braking assemblies, which must withstand higher cumulative thermal and mechanical stresses. Prospective buyers should focus their physical inspection on the braking system to ensure the 2025 advisories were fully addressed. During a test drive, pay close attention to the brake pedal feel for any sponginess or pulsation, which could indicate uneven disc wear or air in the system. Listen for any grinding or squealing noises during low-speed deceleration, which may signal that the rear pads are nearing the end of their service life again. Additionally, check for any pulling to one side under braking, which could suggest a sticking caliper or uneven pad application. Given the high mileage, a thorough inspection of the suspension and steering components is also warranted. Listen for knocks, clunks, or knocks when driving over uneven surfaces or speed bumps, as these are common symptoms of worn suspension bushes, ball joints, or coil springs. It is also advisable to inspect the area around the engine and gearbox for signs of oil misting or leaks, as high-mileage engines often exhibit seal wear that may not yet have triggered an MOT failure but could impact long-term reliability.
