2 Answers
Solutions for BMW Tire Pressure Monitoring RDC malfunction: 1. Sensor or module issues: It is recommended to go to a repair shop for inspection; 2. If it is not a sensor or module issue and the program has not been flashed, simply reset it. Reset before going out, and the car will automatically calibrate after driving for a while. BMW is a German luxury car brand, founded in 1916, headquartered in Munich, Bavaria, Germany. Its car series include i, X, Z, and pure number 4 models, as well as series 1, 2, 3, 4, 5, 6, 7, 8, etc., and the M series based on improvements to each series.
I previously encountered a BMW tire pressure monitoring system (RDC) alert, which was usually caused by a faulty sensor or dead battery. Those sensors are inside the tires and often suffer from impacts or aging. I recommend first checking the tire pressure yourself using a standard pressure gauge on all four wheels. If the readings are normal, try resetting the system: turn off the car, lock the doors, wait a few minutes, and then restart it. Sometimes the alert will disappear. If it persists, it’s likely a sensor issue, possibly due to a drained battery that needs replacement—each sensor usually costs a few hundred bucks. Additionally, software bugs can also cause trouble, so try updating the system settings via iDrive. If all else fails, don’t push your luck—head straight to a 4S shop for professional diagnostics. They’ll use specialized tools to check the wiring and ECU module. Remember to maintain your tires regularly to avoid punctures or impacts, which can reduce such issues. Unstable tire pressure not only wastes fuel but is also dangerous—a blowout at high speed could have dire consequences. I always treat it as a serious matter.
