How to Fix the Tire Pressure Warning on BMW Tires?
3 Answers
BMW tire pressure warning repair method: After restoring the air pressure of all four tires to the standard pressure, press and hold the tire pressure reset button next to the gear lever to fix the tire pressure warning. Tire pressure refers to the air pressure inside the tire, and the level of tire pressure plays a significant role in the performance and power of the car. The BMW 7 Series has a body structure of a 4-door, 5-seat sedan, with body dimensions of 5273mm in length, 1902mm in width, and 1498mm in height, and a wheelbase of 3210mm. The BMW 7 Series is equipped with a 2.0T inline 4-cylinder turbocharged engine, with a maximum power of 195 kilowatts and a maximum torque of 400 Newton-meters, paired with an 8-speed automatic manual transmission.
When the tire pressure warning light comes on while driving a BMW, I find it really annoying. I encountered the same issue last year. After parking, I used a tire pressure gauge to check each tire and found one was only at 1.8 bar, much lower than the recommended 2.2 bar. So, I went to a nearby gas station to inflate it to the standard value. Then, I had to reset the tire pressure warning function in the iDrive system settings on the center console, just follow the prompts step by step. Sometimes the warning isn’t due to low pressure but because the sensor got wet and needs to dry out. Regularly checking tire pressure can also save fuel—I check mine once a month. If the warning light stays on after resetting, visit a 4S shop or a reliable repair shop; it might be a faulty sensor or wiring issue. Don’t keep driving recklessly, it’s dangerous.
I was totally panicked when the tire pressure warning went off. Last time on the highway, it suddenly lit up, and my heart was pounding. I quickly pulled over and checked BMW's standard tire pressure values on my phone—generally 2.2 bar for the front tires and 2.4 bar for the rear. Using a simple tire pressure gauge from the car, I found one tire was indeed leaking. After refilling it, I clicked the reset button in the settings menu on the center console. If you don't have tools, roadside service stations offer free air refills. Don't ignore the warning light—driving on a flat tire at high speeds increases the risk of a blowout and wastes fuel. If you can't handle it yourself, call a tow truck to a repair shop to check if the sensor or electronic module is functioning properly—it won't cost much.
