You need the UGDO, or Universal Garage Door Opener, an option from BMW dealer. Not sure if you have it and need the instructions, or don't have it. If you need the instructions, look here:

Don't worry about the E38, the remotes all work the same.

/ You have three buttons under your mirror...

Turn your ignition switch to the first position...

Then press the outer buttons at the same time until the red light blinks 3 times fast (clears the memory), then one time(signals it is ready).

At that time, depress your garage door opener at the same time as the red light blinks once. You need to hold the garage door opener about one inch from the mirror.

After that, check it out to see if it worked.

If not, either your garage door opener isn't compatible or something else is going on.
Your dealer should have told you how to do it. I believe the brand is homelink %26 you can get more info about how to set it up using homelink.com

To tell you the truth, I would go back to the dealership and ask them because they should know and could teach you how to do it. Should be a pretty simple process that takes no more than 10 minutes.
