Last time when my BMW showed a tire pressure monitoring system (RDC) malfunction, I was really worried. I first pulled over safely on the highway shoulder and checked all four tires with my portable pressure gauge. The pressures were all within BMW's recommended range of 32-35 psi, as clearly stated on the door frame label. After confirming everything was correct, I tried resetting the RDC system through the iDrive vehicle settings menu - the steps were simple but required driving slowly for a few hundred meters for recognition. Unfortunately, the warning light remained on, so I suspected a sensor issue. Online research showed BMW's original sensors typically need battery replacement every 5-6 years, so I went straight to the dealership and spent over 400 yuan to fix it. This whole experience taught me that safety comes first - never risk driving with potential pressure issues that could lead to blowouts or loss of control. Now I manually check tire pressure monthly to avoid similar problems wasting time and money.
