In my M2, the Rear Laser Sensor "sees" anything up to 12 inches or so - your hand when you want to adjust the volume or mute it, a piece of paper, your cold dog's nose, or even the back of the control display or the rearview mirror. The solution? Put a piece of black electrical tape over the round, 1/4-inch Rear Laser Sensor between the Bogey Counter and the Band Identifier Lights. That's it - problem solved - but of course you lose the functionality of rear laser detection, which is minimally useful anyway.
I suspect the V1 is picking up some type of electromagnetic interference from the center of the dash of the M2. If you ran a piece of tape from the lower outside corners of the climate control unit, up over the rearview mirror and to the windshield, you'd define the area where the interference is greatest - but it can false outside of that area too. Some BMWs are known to Valentine as being susceptible to OBD II-related interference (like several other cars) but I don't know if that has anything to do with this issue. I'm going to call Valentine this week.

Thanks for doing the research, Spa. Report back what Valentine has to say. I definitely improved my laser falsing big time by moving the unit to just beneath the mirror. I got one false today as I was backing out of the garage synchronous to the opening of the garage door.. Then, not another laser falsing for the entire 30 mile drive.
