MOST Bus quirk need help

Happy America Day everyone, I am coming to you with a weird problem because I need your help. I have a 2009 e92 that has a TCU, MULF, and SAT Radio. Everything works in regards to sound. AUX, USB, CD, Door Chime, and Key chime with all that working I'm noticing a weird problem with the MOST Bus, everything I read says that with power on if the fiber connector is removed from a module the module should emit a red light however, in my car none of the modules produce this light (and everything works).

Now the reason I'm troubleshooting this is because I am unable to read the MULF can anyone explain to me why I get sound and operation from the USB (MULF module) but can't communicate with the module with NCS Expert.

Any help troubleshooting this is greatly appreciated. Thank you

Run Inpa functional jobs to see if the Mulf
and other Modules can be read. As per bimmerprofs link.
Pretty confusing that you put up a picture of a 750 and also say you are working on a 09 three
series which is it.?!

Did you physically look at it to verify its a mulf 2 hi and not a combox.
