2012 Mercedes-Benz C 2.1L Diesel · FY12 AAU

The most recent DVSA MOT test, conducted on 31 October 2025, returned a pass with no defects or advisories recorded, and the prior test on 2 October 2024 also passed cleanly. The intervening failed tests on 7 August 2024 and 15 May 2023 are recorded with no listed defects, which suggests they were likely withdrawn or did not proceed to a full assessment, or that the results file lacks recorded categories. Either way, the present pattern is one of stable compliance: two consecutive passes with no advisories at the end of the sequence, indicating that the vehicle is presently being maintained to a roadworthy standard. From a buyer perspective, this is a reassuring tail to the record, although the absence of any advisories over the past two tests means there is no documented steer as to which components are beginning to show wear. At 152,205 miles over approximately fourteen years, this C-Class is accumulating around 10,800 miles per year, which is broadly typical for a vehicle of its age and consistent with regular mixed-use driving rather than long-term storage or exceptionally heavy motorway mileage. There are no unusual gaps or sudden jumps in the recorded mileage that would suggest clock irregularities, and the steady accumulation is the kind of pattern that keeps mechanical components, particularly the diesel or petrol combustion system, clutch or automatic transmission, and brake and suspension assemblies, in regular working order rather than suffering the corrosion and fluid degradation associated with prolonged standing. That said, 152,000 miles is a substantial figure for any passenger car, and buyers should anticipate that certain high-wear items will either have been replaced or be approaching the end of their effective service life. Because the official record is unusually clean, with no advisories to point the buyer towards specific components of concern, the inspection will need to be led by age-and-mileage-appropriate judgement. The tyres should be examined closely for sidewall perishing and cracking from age rather than simply tread depth, as a fourteen-year-old sidewall can degrade even on a tyre with plenty of tread remaining, and uneven wear across the axle would point to worn suspension bushes or coil springs, both of which are common failure items on a C-Class at this mileage and would be audible as clonks or knocking over speed humps and uneven surfaces. The brake discs, particularly the rear ones, should be inspected for lipping and corrosion, and the calipers should be confirmed as free-running rather than binding after standing, which would manifest as the car pulling to one side under light braking or excessive brake dust on one wheel. On the test drive, listen for clonks from the front suspension over broken tarmac, judge the steering for vagueness or vibration that would indicate worn wishbones or track rod ends, and confirm that the automatic transmission or manual gearbox changes smoothly without flare, slip, or clonks on engagement. Beyond the mechanical running gear, attention should turn to the time-based service items that the MOT does not cover but are critical at this age and mileage. The 12-volt battery is well past its typical five-year service life and should be load-tested, particularly if the car has been used for short journeys, as a weak cell can leave the vehicle stranded without warning. Brake fluid is hygroscopic and should have been changed at least every two years regardless of mileage, so verify the date stamp and service history. Coolant, transmission fluid, and the differential fluid on the rear-driven Mercedes platform all degrade with calendar age as well as mileage, and given that the record shows no service stamps, a thorough inspection of the service book and any supporting invoices is essential to confirm that these interval-based replacements have actually been carried out. Finally, examine the underside, including the subframe mounting points, suspension arms, and exhaust system, for any surface corrosion that could develop into a structural issue at the next MOT, and check for oil or coolant leaks from the engine and automatic transmission that would be consistent with the sealing wear expected at this mileage.
