The Mystery of the Fog Lights

[edco]

Today was finally a day I could wash my car. No snow, no rain, 50 degrees.
I noticed (without an indicator on the dash) the passenger side fog light bulb was out. No problem, I thought, I'll go buy a new one and install it. It takes all of 5 minutes on a 2011 X5. You pop out these little adornments and you can easily reach you hand in and twist a new bulb.
And I did and it worked. Then as i was walking back, I noticed that now the DS fog light was out. Coincidence? I doubted it. I tested the bulb with a multimeter and found no resistance which meant the filament was unbroken. I also tested the voltage and was getting like 3 volts out of the DS. YET when I put the new bulb in the DS, it worked. So I went back and bought another bulb. Same as the original 55W, And now NEITHER side works.
So I called a buddy who works at BMW and he said it could be the FLM which I believe stands for the Floor Lighting Module and there are no fuses that operate the fog lights (these are the two on the bottom inserted into the front bumper.
AND as it turns out, there have been problems with the FLMs and BMW has extended the warranty to 12 years and 125000 miles.
My car is going in Tuesday, and I will report back, but just in case anyone is having gremlins in their lighting, be aware that there is a "soft recall" out there if you get as perplexed as me.
