Tire Pressure Monitoring System (TPMS) has become a mandatory safety feature in cars. It protects the passengers as well as the car\’s health. Similarly, BMW, a famous German automotive brand has its BMW TPMS sensors.
Moreover, BMW car models include direct or indirect TPMS sensors depending on the car model year. Let’s go through the complete details about the BMW TPMS sensor.
BMW TPMS Sensor
BMW cars come equipped with TPMS sensors as part of the wheel valve assembly. All tires are equipped with TPMS sensors including the spare tire. The sensor measures the pressure and temperature in the tire.
After determining the pressure and temperature, the tire transmits data to the car computer receiver. The data transmitted has a unique ID and if the pressure isn’t according to BMW’s recommendations, a warning light turns on.
BMW TPMS Sensor Fault
A BMW TPMS can become subject to failure due to electrical or mechanical problems. The following problems can cause BMW TPMS faults and require replacement:
- Broken accelerometer
- Low TPMS battery power
- Blocked pressure port
TPMS faults may exist due to negligence at the time of tire servicing or changing. Additionally, when replacing the BMW TPMS sensor, ensure that you use proper TPMS tools.
Let’s go through a brief guide on TPMS service to prevent the BMW TPMS fault after service.ce
BMW TPMS Service
TPMS service and replacement require one to learn the tire pressure sensors basics. Moreover, correct BMW TPMS tools are essential. For instance, if you don’t have the correct tools to scan the fault, it will be difficult to service.
It is recommended to visit a professional when you need a TPMS sensor service. A professional can help with TPMS relearning. Besides, make sure you buy new car TPMS sensors that are compatible with newer BMW models when you change tires.
BMW TPMS Replacement
If the TPMS light turns on, it may be due to a fault. This will require TPMS replacement and the new TPMS will need reprogramming with a unique ID. Besides, check if the TPMS sensor in your car model is external or internal. Also, learn about other types of TPMS sensors for your BMW models.
Additionally, check the valve core materials when performing any tire service. Speaking of that, dissimilar metal valve cores can cause the galvanic correction. Before replacement, make sure to use the TPMS scan tool to check the fault code.
Also, you must have the following guidelines before replacing the BMW TPMS sensors:
- Description and operation of vehicle TPMS system
- Warning indicator reset procedure
- System Relearn procedure
- Dismounting and mounting cautions
- Replacement procedure
- Wheel Nut torques
- Tire Pressure Sensor Nut torques
This wraps the complete guide to the BMW TPMS sensor, its replacement, and its service. You can always look for BMW models compatible TPMS sensors from the leading tire pressure sensor supplier and manufacturer, Porcsi.
