MID Toggle Button not working, DSC Notice?

[270_BMW]

Hey guys, sorry about dropping all these different threads... just different things I have noticed going on here lately.

So when I first got my X5, the "BC" button on the turning signal stick coming off the steering column worked. It has since stopped working, checked all of the fuses and connections that I could find on the steering column but haven't found anything, is it common for these to stop working? Is a replacement for this specific modules possible or do I need to replace the whole turning signal stick?

Also at random intervals and sometimes not at all I will get a notice while driving that says "DSC Inactive" and the Information light stays on until the engine is shut off. When it's turned off for even a moment I guess the information resets. I've seen where the DSC notice is common for the E53 but never found a consistent underlying reason. Note, before this notice pops up I can toggle the DSC without issue, but once the notice comes up I can no longer change it. No noticeable hills in my area short of going across an overpass so it isn't really necessary as far as I can tell.

*Edit

Also I have noticed the manual shift option doesn't not work, the X5 is an automatic, but has the sport shift option.... just doesn't work.
