Bedroom TV no reception?

Hi bcircus------Had the same problem with our 2015 5er. Could not get a signal from the outside sat/cable connection point to the bedroom sat/cable connection point. Living area and bedroom have separate feeds. Living area worked just fine. Not sure if you ever installed a connector on coaxial cable. To prepare you have to remove the outer covering exposing a braid & aluminum shielding, then the insulator foam, cutting away to expose the main center wire that carries the signal. I found my problem at the "connector" on the outside utility compartment. The person who installed the coaxial connector at the factory did not notice the piece of braid wire that wrapped around the center wire, creating a dead short in the signal. Replaced the connector and problem solved. Good Luck -- Hope this helped.
