Does anyone know what the 35d is doing just after engine shut down?

p.s. we have a little over 4k miles on the 35d. Nearly all of our driving involves round trips between 25 and 100+mi. It has not gotten to freezing temps yet here in the Texas Hill Country.

Yes, I have heard these same noises after the car is turned off. I hear a high frequency countinous beep and maybe after 5 mins or so everything shuts down completely. really weird initially I thought my car was trying to transform into one of the bots when I am done driving it
