2021 Mercedes-Benz EQC 400 AMG Line Premium 4M Electric · LP21 WDW

With only two MOT entries on file, both returning a pass with no advisories or defects recorded, this EQC presents a remarkably sparse official roadworthiness record. The most recent test on 22 July 2025 confirmed compliance with no items flagged, and the prior examination in August 2024 was equally clean, so the documented trend is one of consistent pass results without any emerging component concerns being noted by the tester. For a 2021 premium electric SUV now approaching five years of age, the absence of any advisory wear items across two consecutive tests is a positive indicator, though it does limit the depth of historical insight available from the DVSA data alone. Buyers should be aware that the third MOT, due in 2026, will be particularly informative as it is typically the point at which suspension consumables, brake components, and underbody corrosion on Mercedes products begin to surface as advisory items. At 29,065 miles against an age of roughly five years, this vehicle is accumulating mileage at approximately 5,800 miles per year, which is well below the national average and clearly represents light usage. Such a low annual figure suggests either a predominantly urban commute pattern, a vehicle used for occasional longer journeys, or potentially periods of extended standing between uses. While low mileage generally preserves interior trim, brake rotors, and tyre wear, it does place particular demands on items that suffer from lack of use rather than wear; the 12V auxiliary battery, drive unit coolant hoses, and underbody sealing components can all degrade from prolonged standing, and brake discs may develop surface corrosion that leads to judder on the first application after a period of disuse. Any extended gaps in recorded mileage between the MOT tests should be queried, as significant stationary periods on an electric vehicle warrant additional inspection of the high-voltage system seals and the conventional 12V battery health. From a component standpoint, the clean advisory history means there are no specific flagged items to target, yet the test drive and physical inspection should focus on areas typical of this model and age bracket. Pay close attention to the regenerative braking system and the transition to friction braking at low speeds, as Mercedes EQCs are known for inconsistent pedal feel, and listen for any scraping from the rear calipers which can seize due to the regenerative system rarely activating them. On the suspension, push down firmly on each corner and release, checking for any knocking from the front lower control arms or rear multi-link bushings, both of which are common advisory items on Mercedes products once past the three-year mark. Steering should remain precise without vibration through the wheel, and any pulling to one side under braking should be investigated as it may indicate a binding caliper rather than a pad wear issue. Practically, the prospective buyer should commission a battery state of health report from a specialist, as the MOT record provides no visibility into the high-voltage pack condition, which is the single most valuable component on this vehicle. Inspect the underside on a ramp if possible, paying particular attention to the underbody composite panels and the area around the rear electric drive unit for any signs of leakage or impact damage that would not be visible from above. Tyre condition should be examined for flat-spotting from standing, and all four tyres should ideally be of matching brand and tread depth given the all-wheel-drive system's sensitivity to rolling circumference differences. Finally, verify the full Mercedes service history, as the EQC requires specific high-voltage system inspections at two-year intervals regardless of mileage, and any deviation from this schedule could affect both warranty standing and long-term drivetrain reliability.
