This is one of the most common disappointments after importing a Chinese EV, so check before you buy. Many Chinese EVs rely on an embedded SIM that only works on Chinese carrier networks. Once the car leaves China, remote functions — battery status, pre-conditioning, charging control, and locating the car — may stop working entirely. Some brands let you transfer the account to a foreign phone number, but many require a Chinese ID or Chinese phone number for registration, which you cannot provide. What to do before purchase: ask the exporter to test the app functions live on video while the car is still in China, including remote air-conditioning and battery percentage reading. Ask the brand's official customer service (in writing) whether overseas account activation is supported for your specific model and year. Workarounds if the official app does not work: some functions may still operate locally through the car's own settings, such as scheduled charging from the dashboard. Third-party OBD dongles with companion apps can sometimes restore battery monitoring and pre-conditioning. The car itself drives fine without connected services, but if app functionality matters to you, treat it as a purchase criterion, not an afterthought.

The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.

Yes, all external lighting sources, including low beams, high beams, fog lights, daytime running lights, reverse lights, and brake lights, are included in the mandatory power-on testing.
