宝马胎压传感器 6798872-04 实时监测轮胎压力 安全报警

Tire pressure sensor (OEM: 6798872-04) compatible with multiple models including BMW 3 Series, 5 Series, X3, and X5 from 2014–2020, installed at each wheel valve stem. It monitors tire internal pressure and temperature in real time and transmits wirelessly to the vehicle system; if pressure is abnormal or drops rapidly, it immediately triggers a dashboard alert. Installation requires removing the tire and programming; recommended to be performed by a professional technician, with about 30 minutes per wheel. If the dashboard continues to show a TPMS warning, the sensor may be faulty.
