It certainly could be a module problem though I would still do more troubleshooting to eliminate some other potential causes.
Have you used your Peake tool to see if there are any errors in the computer?
Also, BMWs are very sensitive to low or high voltage. The result can be strange things happening similar to what you are experiencing. I would have the battery load tested at a local auto parts store, it's usually free. I would also unlock the cluster and check the battery voltage after it has been sitting overnight and monitor the alternator to see what the voltage is running and watch for voltage less than 13v or over 13.8 or spikes over 14v.
For the future I suggest purchasing the following suite of software:
