What to Do When a BMW Tire Loses Pressure?
2 Answers
First, inspect the tire to check if issues like air leakage are causing the low tire pressure indicator to flash. Press and hold the SET button with the tire pressure symbol located at the far right front of the gear lever for an extended period. After opening, locate the switch button next to the passenger airbag key in the upper left corner inside the glove compartment. With the ignition switch turned on, hold this button until the tire pressure light turns off. This step requires the car's tire pressure to be within the normal range.
Last time I drove my BMW for an outing, I also encountered the tire pressure warning light coming on, which was quite alarming. You must immediately turn on the hazard lights and move the car to the emergency lane. Never push through and keep driving—if the wheel rim gets deformed, the repair costs could easily start at five figures. First, walk around the car to check the condition of all four tires and see if there's a nail stuck in any of them. If the air leakage isn't too severe, you can use the inflator pump from the trunk to temporarily refill the tire and make it to the repair shop. But if the tire is completely flat, just call BMW's emergency assistance hotline—they're on standby 24/7 and will arrive within half an hour. It's always good to keep an emergency light and reflective vest in the car; they're especially useful if you break down late at night.
