02 Sensors - Replace now?
Maybe I will get some more help in this forum:
MY 03/08 E92 M with pullies / test pipes / air filter / Stage II tune. I had issues with my Throttle Valve Actuators and got them replaced under warranty (though had to pay a deductible). Now I have some O2 sensor faults (known to be problematic sometimes) so I just want some help deciphering which ones I need to replace. Here are the codes: 27C7 - Lambda sensor trim control AD diagnostic bank 2 2771 - Lambda sensor dynamic diagnostic VKAT bank 1 From my understanding: VKAT = VOR (before) Cat NKAT = NACH (after) Cat bank 2 = drivers side bank 1 = passenger side Quote:

If it is throwing those codes, I would replace the O2 sensors. It looks like both banks are faulty. Most likely the pre-cat ones.
