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!
