Exclamation Unplugged...

I unplugged the front speaker tonight, and as expected have a malfunction code/warning. I (too) am ok with the rear speaker as I feel it may come in handy here and there.

Having the noise completely eliminated in Drive is bliss compared to that awful noise that was tweaking my equilibrium.

I am open to the best / cleanest solution though. Iím ok with coding (and can plug the front speaker back in) but would like VSG zero noise as the desired outcome. I understand there will be motor whine and tire noise.

Can anyone tell me the proper coding for the unplugged VSG?

If this is not the best route, I can proceed with the solutions noted in this thread, but it sounds (no pun intended) like there is still minimal noise present in the end result...

Last night, I tried to Vehicle Order (VO) code the VSG out by removing the 4U9 option and then FDL coding the ECUs to defaults. All this did was make the VSG essentially sound like a skipping CD player (remember those?). What I did not do was physically unplug the speaker at this point because I don't know where it's located. @Eye3, you may try this to see if that resolves the issue.

If not, I'm still not clear on exactly what to FDL code to get the following results:
  1. No noise output from the VSG speaker at startup
  2. No dash or failure indication

In an ideal world
  • There would be a setting to enable/disable in iDrive
  • That setting would be memorized
  • When the VSG is disabled there would be no warning/malfunction

I'll add that to my knowledge thus far, there are 2x VSG modules with their own settings and also VSG settings within the HU_NBT2 module. I just grabbed the CAFD files last night so haven't had a chance to peruse them offline.
