2022 Mercedes-Benz C 300 E AMG Line Auto 2.0L Hybrid electric · OU72 XJC

The most recent official MOT test for this 2022 Mercedes-Benz C 300 e AMG Line was conducted on 2 October 2025, at which point the vehicle passed with no advisories or defects recorded against it. With only a single test outcome in the official history, there is no longitudinal trend from which to draw firm conclusions about whether maintenance is stable, worsening, or improving. However, a clean pass with no recorded advisories on a four-year-old vehicle is a broadly positive indicator, suggesting that at the time of examination the vehicle met all statutory roadworthiness requirements for braking, suspension, lighting, exhaust emissions, tyres, and structural integrity. The absence of any recorded defects implies no immediate rectification items were flagged, although this should not be interpreted as a substitute for a comprehensive pre-purchase inspection by a qualified technician. The recorded mileage of 37,048 miles over approximately four years equates to an annual average of around 9,262 miles, which is broadly typical for a vehicle of this age and consistent with moderate private or mixed-use driving. There are no obvious extended gaps or sudden mileage spikes in the documented history that would suggest prolonged standing periods or unusually heavy accumulation within a short window. This average usage pattern is generally favourable, as it tends to indicate regular operation, which helps preserve component longevity particularly for the hybrid powertrain, brake discs, and 12V auxiliary battery. Nevertheless, given that hybrid components and conventional ancillaries alike degrade with calendar age as well as mileage, the date of registration remains as relevant a factor as the odometer reading when assessing overall condition. Given the clean MOT record and moderate mileage, the prospective buyer should concentrate on age and time-related deterioration rather than chasing specific failure patterns. Tyre sidewalls should be inspected closely for perishing or cracking caused by UV exposure and age, even where tread depth remains legal, as Mercedes-Benz-fitment tyres on a C-Class are often run-flat specifications that can deteriorate from the outside in. Brake discs, particularly on a hybrid which uses regenerative braking, are susceptible to surface corrosion and caliper binding from extended low-speed use or standing periods, so a test drive should include several firm stops from moderate speed to confirm smooth, vibration-free retardation and no pulling to either side. The 12V auxiliary battery, which is critical for the hybrid control systems, should be load tested, as Mercedes-Benz vehicles of this generation are known for premature auxiliary battery failure that can cause a range of non-start or system fault conditions. Fluid servicing on this powertrain is largely calendar-based rather than purely mileage-driven, and any prospective purchaser should verify the service book history for brake fluid replacement at the recommended two-year intervals, along with coolant and transmission oil changes in line with Mercedes-Benz long-life service schedules. Given the hybrid element, the high-voltage battery thermal management system, including coolant pipes and the associated radiator, should be inspected for leaks or contamination. On the test drive, listen carefully for any suspension clonks or knocks over uneven surfaces, which would suggest worn bushes or top mounts, and pay attention to any vibration through the steering wheel that might indicate imbalance in the front axle given the additional weight of the hybrid components. Finally, a pre-purchase diagnostic scan for any stored fault codes across the high-voltage system, driver assistance systems, and infotainment is highly advisable, as many such issues will not surface during a standard MOT examination but can prove costly if left unaddressed.
