2022 Mercedes-Benz EQC 400 AMG Line Premium + 4M Electricity · SC22 UPD

The most recent DVSA MOT test for this 2022 Mercedes-Benz EQC 400 AMG Line Premium was conducted on 13 June 2025, at which point the vehicle passed with no defects or advisories recorded against it. While a single clean test is reassuring, it is worth noting that the recorded history is relatively sparse, and a clean pass simply reflects the standards enforced at the time of inspection rather than a guarantee of underlying mechanical condition. Given the absence of any recorded advisories or recurring failure points, the immediate maintenance trend appears stable, though prospective buyers should not infer long-term reliability from a solitary test entry alone. The EQC is a relatively new and complex electric SUV, and its roadworthiness extends beyond items traditionally examined under MOT criteria, particularly concerning high-voltage battery health and electric drive components which fall outside the standard test scope. With a recorded mileage of 8,944 miles over approximately four years, this vehicle has covered an average of around 2,236 miles annually, which is notably low for its age and suggests either predominantly short-trip urban use or extended periods of standing. Such low annual mileage carries its own mechanical considerations. While wear on conventional drivetrain components, brake friction material, and tyres will be reduced, vehicles that spend prolonged periods stationary are susceptible to brake disc corrosion, potential caliper binding or seizing due to surface oxidation, and deterioration of rubber and polymer components through age rather than use. Equally, the 12-volt auxiliary battery, which supports the vehicle's electronic systems, is vulnerable to premature failure when subjected to frequent shallow discharge cycles typical of low-use vehicles, and any prospective buyer should verify its age and state of charge. Given the clean MOT history and low recorded mileage, the focus of any pre-purchase inspection should shift toward age-related and standing-related degradation. Tyre sidewalls should be carefully examined for perishing or cracking caused by UV exposure and ozone ageing, even if tread depth remains adequate, as tyres older than five years from their date of manufacture are generally considered to have reduced structural integrity regardless of wear. Brake discs should be inspected for visible surface rust and any evidence of uneven corrosion or pitting, and a test drive should include several firm brake applications from moderate speed to confirm that the brakes bind, release cleanly, and pull evenly without juddering. The condition of any visible suspension components, including coil springs and anti-roll bar bushes, should be checked for cracking or seizing, as these can deteriorate from disuse as readily as from heavy loading. Any warning lights on the instrument cluster, particularly those relating to the high-voltage battery management system, regenerative braking, or driver assistance systems, should be investigated prior to purchase. Finally, because the recorded mileage is unusually low for the vehicle's age, particular attention should be paid to time-based servicing items rather than purely distance-based schedules. Brake fluid is hygroscopic and degrades through moisture absorption over time, typically requiring renewal every two to three years regardless of mileage, and the cooling system for the high-voltage battery and electric drive components should be checked for correct fluid condition and any signs of leakage. Door, boot, and bonnet seals, along with any rubber gaiters on suspension or drivetrain components, should be inspected for hardening or cracking, as these can perish from lack of use and environmental exposure. The cabin and high-voltage battery pre-conditioning systems should be exercised to confirm full operational function, and the vehicle's charging history, including any stored error codes accessible through diagnostic interrogation, should ideally be reviewed. A comprehensive inspection by a specialist conversant with Mercedes-Benz electric vehicles would be strongly advisable to confirm the broader mechanical and electrical condition beyond what the limited MOT history alone can demonstrate.
