Hmm...those are unusual problems. Looks like the common part for both problems is the Light Control Module. You'll probably have to take it into the dealer (or a BMW specialist) to diagnose this.

However, the first thing I would do is check your fuses. If they're OK, then for codes in all modules and see if there is a trail to follow. Many times with this type of problem (multiple failures) the module that controls all of them is defective or has poor wiring to it.

Here is what I did to get rid of the problem - why it worked I do not know - maybe there are capacitors that hold voltage and it took a while to disipitate the current.

I disconnected the battery terminals - waited 24 hours - try hooking up - problem still existed
then
I disconnected the battery terminals and left it for 3 days -
When I connected the battery all was well.
I guess I saved myself a lot of money for the tow, diagnostic and probably replacement of some part that would have not been required. Have put on about 40,000 km since then and no problems.

I guess I got lucky this time - probably not a logical solution - but made sense to me at that time .... why - i don't know - maybe desperation...
