Where is the refrigerant charging port for BMW X1 air conditioning

The location is under the headlight cover panel. The car air conditioning system is charged with refrigerant at the refrigerant storage tank. There are two methods for charging refrigerant into a car air conditioning system: high-pressure side charging, which is suitable after leak detection and vacuum evacuation. Note that the compressor must not be turned on during this method, the engine should be off, and the refrigerant tank needs to be inverted. The other method is low-pressure side charging, where gas is charged. This method is characterized by slower charging speed and is typically used for refrigerant replenishment. Steps for high-pressure side refrigerant charging: 1. When the system is in a vacuum state, close the high and low-pressure manual valves on the manifold gauge. 2. Connect one end of the middle hose to the refrigerant tank injection valve fitting. Then open the refrigerant tank valve, loosen the nut at one end of the manifold gauge hose to let gas escape for a few minutes, then tighten the nut. 3. Open the high-pressure side manual valve and invert the refrigerant tank. 4. Inject the specified amount of liquid refrigerant from the high-pressure side. After closing the refrigerant tank injection valve and the high-pressure manual valve on the manifold gauge, remove the gauge. When charging refrigerant from the high-pressure side, the engine should be off (compressor not running), and do not open the low-pressure manual valve on the manifold gauge to prevent hydraulic shock. Steps for low-pressure side refrigerant charging: 1. First, connect the manifold gauge to the compressor and refrigerant tank properly. 2. Open the refrigerant tank, loosen the nut of the middle charging hose on the manifold gauge until you hear the sound of refrigerant vapor flowing, then tighten the nut to expel air from the charging hose. 3. Open the low-pressure manual valve to let refrigerant enter the system. When system pressure reaches 0.4MPa, close the low-pressure manual valve. 4. Start the engine, turn on the AC switch, and set both the blower switch and temperature control switch to maximum. 5. Open the manual valve on the manifold gauge to let more refrigerant enter the system until the specified amount is reached. 6. After charging the specified amount, observe through the sight glass. If there are no bubbles and no excess refrigerant, adjust engine speed to 2000r/min with blower at maximum speed. The low-side pressure should be 0.147-0.192MPa, and high-side pressure should be 1.37-1.67MPa.
