Hence why I specified the additional IR/ToF units excluding the Rain/Solar Sensor since that's been around for so long. Instead of guessing, grab a roll of electrical tape and determine which is the issue. With different options come different sources.
Front false radar is probably limited to Active Driving Assistant Professional when Intersection Collision Warning is Active.

All quiet. I don't think the laser is going to be hindered at all.

Lol. Yes pretty ghetto but clever.
The rear laser sensor is between the number counter and the band identifier. About center of the detector. The tinted window on the right is the rear radar horn antenna. If this truly does the trick, could be a reflected IR output from something on the dash or the center console.
I'd try covering the console and areas of the dash to see if you can narrow it down. Cover with an opaque solid material where the IR cannot bleed through. |
That won't work for Gesture Recognition false rear Laser. There's nowhere to mount it that doesn't place the detector sensor within the cabin IR zone. That would resolve the touchscreen scatter IR false returns. |
I agree you've identified the obvious sources. After reading this thread I'm leaning towards an unconventional source of IR. Maybe something mounted in the console or overhead lamp assembly.... I'm thinking outside the box on this at the moment.
Others have said they disabled gesture control and it still falsed. However disabling the option might not disable the hardware.... In which case pulling fuses might be required to eliminate potential sources. |
Turning Gesture Control off only disables response, it does not shut the system off.
Touchscreen is also a culprit due to scatter and as has been mentioned, scatter from the Driver Monitoring Camera bouncing off the driver.
There is no need to pull fuses when electrical tape works where hardware cannot be disabled. |
Then where would you put electrical tape to block any IR from gesture control?
Pulling fuses gives you a definitive answer as to whether a system is on or off.
Another poster already said they get flashing and they don't have the driver monitor camera in their car.
Meanwhile my V1 has no falsing trouble in a 540i with gesture control. Maybe the new X5 has Gen 2 hardware? |
You'd cover the Gesture Recognition Camera and IR emitters (#1 on the overhead control).
For touchscreen, there's 3x transmitters/receivers clustered on either side of the screen.
V1 with rear laser enabled in a G30 with Gesture Recognition and no false alerts? That would be a first. |
The V1 has only been in the car once for a road trip, over a couple days. Otherwise it's not used much due to Waze being a suitable alternative.
I know the V1 laser sensor works because I've tested it with an IR emitter.
