Forward Collision Warrning Beeps

After I got my car back from the dealer a few weeks ago, I noticed that my pre-collision warning no longer beeps at me. Only the red car symbol comes on the HUD. Does anyone know how to set the beeping sound on?

maybe it got set to early warning, in this setting the car will just display the red car in the HUD and then when you get too close it will display the red car and beep..
i would deactivate and reactive the system to reset the collision warning system.

Have you tried rear ending someone? If you hit them and don't get a beep, that would confirm a problem. Please report back so we get some follow up. Thanks!

Yeah bumping someone or something would do it. I know my pre collision sensor went crazy our last el nino on the freeway, think it had something to do with the sensor getting flooded with water, went it settled down it was fine

OK. Reporting back. I have to weave in an out of traffic like getting away from the cops in order to make the warning system beep at me. No rear ends necessary . . . just close calls.

My bimmer is back to normal now.
