Fault Code Knowledge Wanted

Looking to purchase a 2014 X3 Xdrive 35i. Had a mechanic do a 3 hour inspection on the vehicle.
He came back with 5 codes. Can anybody tell me what these are and what the problem could be. Can anybody tell me if any of the codes would be enough of an issue to not purchase the vehicle.

Fault codes all listed as Intermittent

180001 Catalytic converter: efficiency below limit value

4809AB Dynamic Stability Control (DSC): Undervoltage in vehicle

9308B0 Identification transmitter: Undervoltage, battery

801A4C SINE: Undervoltage Detected in internal voltage supply

B7F323 Telematics communication box (TCB): Airbag alive signal defective

Thanks in advance.

Undervoltage codes could mean you need a new battery.

Mein Auto:
I was doing some research last night and found a fault decoder. The 180001 and B7F323 have me weary. Scanned the vehicle and live data states the O2 sensors are OK and tapping on the catalytic converter there is nothing to be alarmed about. Confusing. The airbag is an issue as well. Modules are sort of expensive and I don't want to have rip the dash apart. 801A4C is the alarm backup battery. I have no idea where it is located and as I said I don't want to tear the dash apart. 9308B0 is the keyfob battery. Easy peasy. 4809AB is definitely battery related. They all could be due to the battery as well. I'm going to look into it. Thank you for replying and sharing your thoughts. Appreciated.
