2023 Mercedes-Benz EQC 400 AMG Line 4MATIC Electricity · PR54 DMS

The most recent MOT, carried out on 27 March 2026, was passed. The only comment recorded was an advisory that the near‑side front outer tyre is worn close to the legal minimum tread depth and shows edge wear. No failures were logged, indicating that the vehicle’s fundamental safety systems – brakes, suspension, lights and emissions – were deemed satisfactory at the time of testing. With a single MOT entry available, the maintenance trend appears stable, though the tyre advisory suggests at least one consumable is approaching the end of its service life. At three years old the EQC has logged 21,289 miles, equating to roughly 7,100 miles per annum. This figure sits comfortably within the typical UK usage pattern for a premium electric SUV and does not imply any abnormal stress on drivetrain or brake components. The mileage is modest enough that major wear items such as the high‑voltage battery, electric motor bearings and chassis components are unlikely to have suffered accelerated degradation, provided the car has not been subjected to excessive short‑run cycles or frequent high‑speed charging that can raise thermal load. Prospective buyers should give immediate attention to the front outer tyre. Verify the tread depth with a gauge; if it is below 1.6 mm or exhibits pronounced edge cupping, replace the tyre and have the wheel alignment checked to prevent uneven wear on the remaining set. While on the road, listen for any low‑frequency thumps or vibrations that may indicate a developing suspension bush or steering knuckle issue, especially when cornering or braking. Because the vehicle is an electric model, also inspect the brake discs for any uneven wear or glazing, as regenerative braking can sometimes mask early disc corrosion, which may become audible as a shudder when the friction brakes are applied after a long stop. Beyond the tyre, conduct a thorough visual and tactile inspection of age‑related items. Examine the rubber seals around the high‑voltage charging port, door hinges and window regulators for cracking or perishing, as prolonged standing can dry out these compounds. Check the 12 V auxiliary battery voltage and load capacity, as a three‑year‑old unit may have lost a significant portion of its charge holding ability. Verify that coolant levels in the thermal management system are correct and that there are no signs of leaks around the inverter and motor housing. Finally, confirm that the service book contains the recommended interval checks for the high‑voltage battery health and software updates, and request a recent diagnostic read‑out to ensure the battery state‑of‑health is within the manufacturer’s specification.
