My 330ci is being very weird

When my car sits for awhile and i get in and drive its ok. But after 5 min, the fog light and door open part of the cluster turns off. my signals work but it doesnt show up on the cluster when im signaling. the doors just lock themselves. the deck says "disabled". and then when i stop and get out, my remote wont lock or unlock the doors. eventually it locks but when it finally works, the lights dont flash anymore. does anybody have any idea what this could be?

Sounds like your body control module(BCM) is giving up on you.

First think you should do in the bonnet(under the hood) on the driver side there is black cover the 4 hex screws. open it there will be 2 aluminum cover boxes and bunch of relays. See if there moisture or water on any components. if get there then dry everything and try again.

Second try reseting the BCM unhook the battery let it sit for 20-30 seconds and power it up.

Then report back.
