I have been having issues with my BMW 3 Series transmission and I suspect it may be due to a faulty transmission control module. How can I reset the TCM to see if that resolves the issue?
ReplyFirst, you will need to disconnect the negative terminal of your car's battery to clear the TCM's memory. Wait at least 30 minutes before reconnecting it. Then, start your car and let it idle for a few minutes to allow the TCM to relearn your driving habits. If the issue persists, you may need to take your car to a certified mechanic for further diagnosis.
Another option is to use a BMW diagnostic tool to clear the TCM's memory. This can be a more precise and efficient way to reset the TCM, but it may require specialized equipment or knowledge. Make sure to consult a professional if you are not familiar with using diagnostic tools.
