Looking at a pre-owned GL and got a PPI done. These were some of the fault codes that popped up. The shop thought they might be from a battery that was going out.

Any thoughts? I posted this in the GL forum as well, but figured this would be a better place.

Whenever I have a vehicle that is running/driving perfect but has codes like that it is presumed that at one point it was jumped, or that the battery was dead or low. I would clear the codes and see if they return.. Everything points to voltage, and that either means bad battery, bad alternator, or the battery ran dead for whatever reason, and had to be jumped..

Thank you. That seems to be the consensus. I was able to talk to a friend at my local mb dealer and he said as long as there wasn't any warnings or CEL showing currently, it was probably due to a battery issue. And I know for a fact this truck has been sitting for a while.

Hi,
I have almost the same error codes in my Gl350.
Did you tried to clear these codes? I am wondering if I should clear it and re-check after some time if are still detected by my vehicle.

best regards
PJ

start with good voltage

Yes, my truck was sitting without driving for a while.
Battery could be very low.

I have opportunity to erase these codes by myself, but I am not sure if I should clear it or leave it for further verification. Despite these codes everything is working without problems.

You have a screen, no need
anyone having a bad battery or battery disconnect , take a screen if you want (99% useless), always erase your faults first; Then run the engine, drive a mile, and run diagnostics
tons of false faults will appear with low batteries. having bad batteries is very toxic for your modules
