The complexity of the system will first require scanning the car with the proprietary BMW scanning tool to uncover the problem. The convertible top is monitored and the data is on a communication bus. Trying to make adjustments on your own without scan data and knowledge of the system is not recommended.

Thanks for the quick help. I fail to mention that it is a manual convertible top so I am not sure if any data is being monitored. By just looking at it, seems like there got to be a way to adjust the cable. If I can't fix it myself I'll take it in to the dealership. Thanks for any help.

Thanks. I can't figure out how I can adjust the cable of the manual top. So if I don't get any addition instruction help here then I have to take it in to the dealership. Thanks in advance.
