2014 Mercedes-Benz C 2.1L Diesel · FH64 KXN

Across the last five consecutive MOT tests from February 2022 through February 2026, this Mercedes-Benz C-Class has returned a clean pass on every occasion and recorded no advisories, defects, or failures of any kind. This is an uncommon and reassuring outcome, particularly given the vehicle's age of twelve years, indicating that the car has remained structurally sound and mechanically compliant through a full cycle of annual roadworthiness examinations. The most recent test on 14 February 2026 confirms this trend, with a straightforward pass and no items flagged for attention. The absence of recorded advisories across five tests means no components were identified as approaching the minimum legal threshold, and no corrosion, wear patterns, or fluid leaks were deemed serious enough for the tester to note. With 152,551 miles recorded against a twelve-year lifespan, the vehicle has covered approximately 12,713 miles annually, which is on the higher side for its age and well above the typical 8,000 to 10,000 miles per year often seen on private vehicles. The mileage gap between successive tests is steady and consistent, with no recorded breaks in testing history that might indicate a long period off the road, SORN status, or odometer irregularities. From a purely mechanical standpoint, this pattern points to regular sustained use rather than short-trip abuse or extended standing, both of which can independently damage certain components. Higher annual mileage generally accelerates wear on consumables such as brake pads and discs, tyres, drive belts, and suspension bushes, but it also tends to keep the drivetrain lubricated and the battery in a healthier state of charge compared to a vehicle that is left idle for extended periods. Given the clean MOT record, there are no specific flagged components to target on inspection, but the high recorded mileage warrants a close mechanical survey of the areas that absorb wear on a heavily used executive saloon. On a test drive, listen for any clonking or knocking from the front suspension over uneven road surfaces, which can indicate worn lower control arm bushes, drop link deterioration, or coil spring fatigue, all common on C-Class chassis at this mileage. The steering should feel precise and self-centring without vibration through the wheel under braking, which would otherwise point to warped front brake discs or worn suspension geometry. Brake pedal feel should be firm and consistent, with no sponginess or excessive travel, and the car should pull up in a straight line without any lateral pull. Under the bonnet, inspect for any signs of oil seepage around the cylinder head cover, turbocharger oil feed lines, and the front crankcase seal, as Mercedes four-cylinder and diesel variants in particular are known for these leaks once mileage reaches six figures. Check the condition of the coolant expansion tank and look for any staining on the radiator or intercooler that could suggest a slow leak. Inspect the underside of the vehicle, paying particular attention to the front subframe mounting points, brake pipe corrosion along the chassis rails, and the condition of the exhaust system, especially the mounting rubbers and flex joint. Tyres should be examined for even shoulder wear across both axles, as uneven wear can reveal worn rear suspension bushes or tracking issues. Finally, confirm that all dashboard warning lights extinguish promptly on startup and that the gearbox, whether manual or automatic, changes smoothly without hesitation or flaring, as these are reliable indicators of an otherwise unrecorded internal wear pattern on a high-mileage but consistently maintained vehicle of this type.
