P2180 & P2178 O2 Sensor codes
My generic scanner reads P2178 and P2180 as "System too Rich off idle."
On the internet, I found these codes from other BMW models which seem similar to mine.
P1178 O2 Sensor Signal Circuit Slow Switching From Rich to Lean (Bank 1 Sensor 1)
P1180 O2 Sensor Signal Circuit Slow Switching From Rich to Lean (Bank 1 Sensor 2)
My question is, am I looking at tracking down about 10 different things that could be causing the O2 sensors to give these errors? Meaning I'll happily replace the O2 sensors, but I'm not real big on throwing parts at my car unless I'm pretty sure it will cure the issue.
One final note, I can actually make these error codes happen. I can clear the codes, drive forever and receive no codes. But the moment I accelerate hard from a stop light, they come on with the Check Engine Light.
any experience with the issue is appreciated!
