My 2 cents--it was the LCM on my 89 525i that caused my
driver side low beam to visit me when it wanted to.
BTW, all your lights are controlled by this little
Hella circuit card. I had the car going in for an
inspection anyway, so i asked them to look at the lo
beam problem too. They resoldered the legs of all the
relays (charged me $50 labor) and it worked great for
about 2 weeks, then same thing again. This time i checked
it out myself...it looked like Ray Charles did the soldering.
I removed the globs and re-soldered it. I also put a small
wedge of foam rubber on the edge of the circuit card since
i believe it's the constant vibration of this card in its
little plastic box that causes the solder to crack. Anyway,
it's been almost 2 years without an LCM problem. And no, i
didn't get my $50 back....yet.

I had exactly the same problem with my 89 525iA. It turned
out that the soldering had cracked at the control unit and
it was a minor job for my shop to re-solder the connections.
That was about two years ago with no problems since.
