My 2012 E92 M3 recently started showing this "Increased emissions!" warning along with the yellow engine symbol on the dash. They last for a couple of seconds before they are replaced by a permanent "Service Engine Soon" light on the dash. I pulled the codes from the car and this is what it showed:

I'm thinking it might be a bad O2 sensor? The car turns on and runs fine, no limp mode or anything. It's just getting those errors every time.

I would appreciate any help!

Likely the pre-cat oxygen sensor in bank 2. If not, then the post cat. Both are faulting.

Should I just change both? Is it safe to drive it meanwhile?

I'd change the precat sensor first, and yes it should be fine.
