Here is my question. I have scoured the interwebz for an answer before posting here. I just updated my 3.0 X5 with a 4.8iS bumper that came with PDC sensors. I have a 2004 (Build date 4/2004) and the harness from the bumper plugged directly into the prewired harness in the spare tire cargo area. There is no PDC module but the wiring exists so I ordered the module and the rear gong (also prewired).
So here is my question. What does the switch on the console do and is it neccessary? My reading shows it is used for diagnostics (blinking) and disabling the front sensors? Since I do not have the front sensors or bumper, will the PDC work rear only without the console switch? TIA for any knowledege from our family. Thanks again.

I just finished PDC retrofit on my daughter's 2004 X5 and all went smooth (console switch box with the PDC button, module, rear speaker, rear and front harness with sensors). I retrofit the bottom part from a 4.8is which has the sensors. The top bumper part was damaged.
The PDC will stop working if one sensor goes bad. So, this answers one of your questions, the rear will not work until you get the front sensors up and running. I use the console switch to turn on PDC manually for front mostly and when I want to stop the beeping for certain reasons. If it stops the fronts, I don't know how.
