2012 Mercedes-Benz C 2.1L Diesel · YF12 BHV

The most recent MOT test on 28 July 2026 resulted in a pass, but it is worth noting that the same date also shows a failed test entry, which suggests the vehicle was initially refused before a subsequent re-test or re-presentation was carried out and passed. Either way, the latest pass was issued alongside five advisories, which collectively point toward a vehicle showing clear signs of age-related wear. Looking back across the 2024, 2025, and 2026 test cycles, the maintenance trend is noticeably worsening. The 2024 test was entirely clean, but the 2025 pass introduced advisories for sub-frame corrosion, steering rack play, coil spring corrosion, and tyre wear, alongside brake disc wear. By 2026, these issues have either persisted or been joined by new advisories covering brake hose corrosion, a binding offside rear brake, and continued steering rack play. This progressive accumulation of advisories over three consecutive tests indicates that while the car remains roadworthy, its underlying components are deteriorating and warrant close attention. With 88,203 miles recorded on a 2012 Mercedes-Benz C-Class, the vehicle has covered approximately 6,300 miles per year, which is broadly typical for its age. There is no evidence in the MOT record of unusual mileage gaps or rapid accumulation, suggesting consistent usage over the years. At this mileage on a fourteen-year-old Mercedes, one would expect the engine, gearbox, and major drivetrain components to have already been exposed to significant wear, even if the annual rate appears moderate. The consistency of use is generally favourable, as vehicles that are regularly driven tend to suffer less from issues associated with prolonged standing, such as seized calipers, deteriorated fluids, and corroded underbody components, though the advisories below show that even regularly driven examples of this age are now developing structural and chassis concerns. Several recurring advisories deserve close scrutiny from a prospective buyer. The rear sub-frame corrosion, noted in both 2025 and 2026, should be physically inspected to confirm it has not progressed beyond the advisory threshold, as sub-frame corrosion on a Mercedes of this era can escalate quickly and ultimately compromise structural integrity. The nearside front steering rack inner joint play has shifted from offside in 2025 to nearside in 2026, suggesting the inner tie-rod or rack bush is wearing progressively; on a test drive, listen for clunking or knocking over uneven surfaces and check for vagueness or wandering in the steering. The nearside rear coil spring corrosion, again noted in 2026, is a common issue on older Mercedes vehicles and can lead to spring fracture if left unchecked, so a thorough visual inspection underneath is advisable. The offside rear brake binding advisory is also concerning, as a seizing caliper or handbrake mechanism will cause uneven braking, potential rear brake drag, and accelerated pad and disc wear, so the car should be test-driven with attention to whether the vehicle pulls to one side or shows excessive heat from the rear wheels after driving. Beyond the advisory items, the brake hose ferrule corrosion and general brake disc wear noted across both 2025 and 2026 suggest the braking system is approaching a period of more significant expenditure. Given the age and mileage, a prospective buyer should also verify the condition of age-sensitive items not necessarily covered by MOT testing, including the 12V battery health, the state of all brake and coolant fluid, the condition of the cambelt or timing chain service history, and any evidence of oil leaks from the engine or automatic transmission. Tyres on a vehicle of this age should be checked for sidewall perishing and cracking even if tread depth appears adequate, and the underbody should be examined on a ramp for any widespread corrosion beyond the already-documented sub-frame. Finally, a full Mercedes-Benz specialist service history stamp verification would be highly valuable, as the progressive nature of the advisories suggests the car may benefit from a comprehensive suspension and brake refurbishment in the near term to restore its mechanical condition to a more reassuring level.
