Looking at buying an X and I just scanned the OBD and this came up...
Is this trouble?

 

[VintageX]

I did some testing and the Bluetooth, GPS and XM antenna do work... Do these codes often just pop up?

 

[VintageX]

Do maybe these happen after a battery failure? Or maybe if the stereo head unit has been unplugged?

No, and yes.
Codes do not just pop up, most of the time.
A battery failur can cause all types of codes, and sometimes not.
The best way to tell would be to clear the codes and see what, if any, recode. If your scan tool can run CAN test even better.

I'm thinking maybe the radio was put back in by the seller and maybe that cause the codes? I didnt look in detail, is it possible to find out the date the codes occurred?

 

[Jard]

Not to my knowledge.
A factory scan tool may be able to.

 

[mtnbound]

can you clear them and if so do they come back?

If you're using the android app called "Torque", I believe there is a register you can read for "Last time MIL was cleared". It will tell you how long its been since the last time all the code were cleared. This could give you an idea how long these codes have been on there for.

Might be helpful.

I use OBDLink and it indicated a couple thousand miles since the last reset. I could not find any way to tell when the codes popped up.
I ended up leaving the codes, I didn't clear them. And I asked the seller (carmax) to investigate them. Actually, I expect they will just clear them, but I wanted them to see and record that they were there in case they pop back up.
But I feel pretty confident it's all head unit related.
