2024 Mercedes-Benz CLA 250 AMG Line Premium E A Hybrid electric (clean) · WN74 LOD

As a 2024 registration, the Mercedes-Benz CLA 250e is still within its first three years of life and therefore does not yet require an MOT test under current DVSA regulations, which mandate compulsory testing only once a vehicle reaches three years of age. Consequently, no MOT history is available, and there are no recorded pass results, advisories, or failure points to evaluate. While the absence of an MOT certificate is entirely normal and expected for a vehicle of this age, it means that the prospective buyer cannot rely on government inspection records to confirm the mechanical condition of the car. Any assessment of roadworthiness must therefore be derived from independent pre-purchase inspection, service documentation, and a thorough physical evaluation rather than from official test data. The recorded mileage for this vehicle is currently unknown, and there is insufficient data to establish an accurate annual usage rate or to compare accumulated distance with the vehicle's two-year age. For a modern Mercedes-Benz CLA 250e plug-in hybrid, an average annual mileage of between 8,000 and 12,000 miles would be considered typical for a combination of urban commuting and longer journeys. The buyer should request verified mileage records from the seller, including service book stamps, digital service histories accessible through Mercedes-Benz, and any previous MOT or pre-delivery inspection records that may have been issued voluntarily by a franchised dealer. Significant mileage gaps or unusually low readings could indicate prolonged periods of standing, which carry their own mechanical implications for a hybrid vehicle, including potential degradation of the high-voltage traction battery if left unused for extended intervals. Given that no MOT defects or advisories exist for this vehicle, the prospective buyer should focus on age and usage-appropriate physical checks that are particularly relevant to a relatively new but potentially lightly used premium hybrid. The 12-volt auxiliary battery, which supports the vehicle's onboard electronics and hybrid system initialisation, should be tested for state of charge and cranking performance, as modern vehicles with complex electrical architectures are particularly sensitive to low-voltage battery failure. Tyres should be inspected for sidewall perishing or cracking from age rather than wear, paying particular attention to the premium low-rolling-resistance fitments typically specified by Mercedes-Benz, which can degrade structurally even with adequate tread depth. The high-voltage lithium-ion traction battery should be verified for state of health, ideally through a Mercedes-Benz diagnostic session, as prolonged standing or frequent shallow charging cycles can accelerate capacity loss in plug-in hybrid powertrains. Additionally, the brake system on a plug-in hybrid warrants particular scrutiny because regenerative braking reduces wear on the friction components but can lead to corrosion of the brake discs and potential caliper binding from infrequent use of the mechanical braking system. The discs should be examined for surface rust and pitting, and the calipers should be checked for free movement and even pad wear. All vehicle fluids, including brake fluid, coolant, and the automatic transmission fluid for the dual-clutch or continuously variable transmission, are subject to calendar-based degradation regardless of mileage and should be confirmed as recently serviced according to Mercedes-Benz flexible service intervals. Finally, given the complexity and cost of Mercedes-Benz hybrid powertrains, it is strongly advisable to commission an independent inspection by a specialist familiar with the brand's 250e architecture, ideally supplemented by a Mercedes-Benz official used car check or a diagnostic readout using the STAR diagnostic system to verify the integrity of the hybrid components, the high-voltage charging system, and the software calibrations.
