Need help plz 🙏. Power management issue

[deboelduro]

Hello members. I’m experiencing an issue after getting this vehicle road worthy

BMW X5 4.8 2009 /Just figured out ISTA and scanned for fault codes, got this:
CDA2 (power management, battery voltage 0x3B4) faulty, receiver DME, transmitter CAS/PM.
CDA3 (power management, battery voltage 0x334) faulty, receiver DME, transmitter
2F80 DME: System time, plausibility
+
Whenever i try to check on service function tab > voltage supply > evaluating the battery state of charge it shows the following:
Engine control cannot recognize IBS. This may be due the following cause:
.IBS supply interrupted
.BSD between DME/DDE and IBS (open circuit, short circuit, loose contact)

I keep getting a check engine light because of this. Anyone had this issue before?
