My car was throwing these codes. I cleared the code, put the stock air intake on it. Drive it for a day or two. Smogged it, and passed. After passing I out the KNN intake back on it and sure enough the sel came back on.

Just so we understand what you’re saying here, you blame a conical air filter for causing your post-cat O2 efficiency codes.
There is no logical relationship between the two elements, unless you dipped your filter in oil.

More than likely you’re sending power to one or more sensors (MAF) while they are disconnected, or your catalytic converters/post-cat sensors are indeed bad – and the code was thrown without any correlation to the intake variable.

Which monitors are incomplete?

Are you saying we're allowed 2 monitors to be with issues?

Catalyst o2 heater and another o2 thingy. Evap went away after 300km's of driving. If you have a 2000 or older you can have 2 incomplete my mechanic says

They are the precats i believe. I just bought them also. They were from a scrapyard and were marked bank 1 sensor 1 and bank 2 sensor 1. I didnt pay attention to that when installing them just plugged em in. I hear from friends that it is all "universal" so it doesnt matter if they get switched around? Anyone! Ive noticed some sputtering at low rpms so could that be it?

Universal O2's definetly exist for the BMW as well, but my bet is they will be terrible at their job.

We tried these universal solutions on an old family car, and they lasted about 2 weeks before switching to OEM.

No I am not "blaming" the conical air filter. However, after I put the stock air filter on the car the code went off an stayed off. Ran it through smog and passed with flying colors. After I put the KNN filter back in ( I am assuming the oil from the filter was throwing the MAF off and it started running rich AND lean) causing it to throw the bad cat code.

So what's the deal with these O2-sims? From what I've lurked through the fourms, it seems the post-cat O2's check for a lean condition after you let off the throttle. These O2 sims do not produce this signal and therefore you get the CEL again.

Straight beamin, I'm looking at you, what was the final outcome of trying to pass your e-test?

The truth is the CEL stay's off and the DME is tricked. But in the past, there where issues with the monitors not in a ready state. the 02 sims DO produce the correct signal, its the monitoring test for when people go take their emissions test that seams to be a hit or miss. I would have mitigated the issue, but my car is lazy at detecting, and I don't have anyone l local to be the ginnie pig

I don't think the OEM o2s were interchangeable. If you skipped BMW and went straight to bosch to purchase your o2s, the pre cat and post cat have different part numbers. for the most part, visually they look the same. the only difference that i could see visually is the length of the wire, since they have to go different distances.

I'm not following why your talking about 02 sensors pacifically? The pre + post 02's are different on how they read, along with their connectors pre is (female) and post is (male) on non-Ms
