Reasons why the BMW BC button cannot be switched?
2 Answers
BMW bc button cannot be switched may be because the frequency is not at 9KHz or 10KHz during BC segment operation. The following is an extended introduction about BC: 1. Origin: The one-button start originally came from the BMW 7 Series, which is undoubtedly a configuration that only luxury models deserve. 2. Development: Nowadays, with the development of automobile consumption trends and the trend of high-end technology extending to ordinary family cars, more and more family cars are also equipped with this technological configuration. 3. Function: In fact, the one-button start not only eliminates the hassle of carrying keys everywhere, but is also one of the symbols of business people and fashion trendsetters staying at the forefront of the times.
A few days ago, my friend's F30 also experienced BC button failure, which was traced to the wiring connector of the steering column module. This module connects to the steering wheel control buttons, and a loose or poor contact in the connector can cause the buttons to become unresponsive. I've also encountered cases where the button got stuck—coffee spilled into the gaps caused the button to jam, but it worked fine after cleaning. The most troublesome issue is wear on the internal membrane circuit of the button, which requires replacing the entire switch assembly. I recommend first checking the menu settings to see if the function was accidentally disabled before troubleshooting hardware issues. While this fault doesn't affect driving, it's quite annoying, so it's better to address it promptly.
