Check the alternator is now charging properly after having the bad battery replaced. Check the cluster memory for fault codes.

Well like I said when the car starts via the instrument cluster test the voltage jumps to about 14v which to me would seem like the alternator is working properly and short of me removing the alternator and taking it somewhere to get it tested I don't know how else to test it (other than maybe checking the voltage across the battery or at the leads in the front engine compartment?)

As for checking for fault codes Ill go do that right now. Are there any specific sensors I should be looking at for fault codes?

EDIT: Okay so I ran my BMW Scanner 1.4 on the X5 and this is what I got;
Scan Codes BMW X5 - Album on Imgur

Images are labeled with what they are and such, also sorry for the camera photos my laptop wasn't letting me take screenshots for whatever reason. Something I also noticed is like I said in my first post notice how MFL, PDC, RAD, TEL, and NAV modules come back as not found? Well I know my car has those from previous code scans and they used to show no errors now they are not even showing up.

Just for schitz & giggles, do the visor test (google it). If it's positive, it might be the ignition switch.

Problem is, and I forget if I put this in the original post or not but I did just replace the ignition switch thinking it was that. I dunno what the chances are of me getting a bad one but yeah...

EDIT: Just did the visor test. Visors and lights work just fine no issues with those and nothing happened when opening up either side.

What is the error in the cluster that is reported? The indicator lights sounds like when our LKM died. All sorts of weird dash lights, no blinkers, no low beams and nothing on the dash.

88 [136] - Instrumentation Bus (I-bus) is the error. On image number 3.

Two readings:
Over current in cluster and data error with LCM. Fault codes for the LCM are stored in the cluster memory. Cluster problem, LCM problem, I-bus problem or combination thereof?
Pretty weird problem.
GL.

Thanks though that doesn't help me much... Could it be possible that a broken/out angel eye in one of my headlights cause this if it's short circuiting? Recently I had one go out on me and it's wasn't a huge importance to replace it. But with that coming from the LCM maybe it's shorting or something? Also I did just replace the LCM about a year ago when I was having headlight issues. So I'd hope/doubt it would be the LCM.

Is there anyway to test what's going on like pull fuses?

Do the simple/easy things first: Replace the AE.
Did you go new or used for the LCM? Check the LCM/cluster connections. Check for water ingress/damage to the LCM.

Well Ill so that as soon as I can, unfortunately right now its raining and will for the next few days so I wont be able to work on the car until it stops along with that I really don't have time to be tearing it apart right now. Next week I might just take it to my mechanic and have him take a look at it or ask and see if he has any ideas about it. I love this thing to death but these little issues are really starting to get to me.
