Which oxygen sensors did you use, universal Bosch, oem-fit Bosch, or BMW part counter?

Did you drive steady speed 20-30 mph (local road) for 4 minutes and steady speed 40-60 mph (highway) for 15 minutes?

Did you get it tested at a good shop? I've taken my car to so many places and there's only one shop in town that can maintain a certain speed on the dyno to get it to pass here in Cali

It's Arizona, 1996 and newer don't require dyno all they do is check for codes and readiness monitors as well as gas cap test that's it

You don't have to do all of the drive cycle. Try to do the drive cycle portion that apply to the o2 sensors. My o2 and o2 heated were the last to get ready. I attempted the drive cycle portions 3 times to get them to pass, but had to do the first portion in yhe morning with engine cold. Did you leave your car in gear, ac on for 3 min when you started your car.

Yes BMWs are complicated. What they want is a large load on the car when in this cycle. So for you I would turn your lights on, Rear Defroster and fan speed to mid-high with your foot on the brake pedal. I used a OBD2 code reader to see the ready/not ready when I did it to see them get READY.

Why did you replace O2 sensors in the first place?
How long have you driven since O2 sensor replacement?
If it is just a few days, you can drive some more.
What code scanner do you have?

They were replaced 6 months ago when I did the engine swap. I have a obDlink mx, from scan tools.net with there free app that allows me to see pretty much everything.

Drive cycle 3-4 times likely will not be good enough.

Did you have CEL & Codes for O2 sensors before you replaced the O2 sensors?? Or did you have CEL & Codes for O2 sensors lately?

If you have CEL & Codes for O2 sensors lately, even when you clear the codes I find that at times it takes longer for the readiness monitors to clear as I believe the DME kind of wants to wait a bit longer to clear readiness monitors anything that had recently triggered a CEL & Codes.

You sure the engine is operating at the proper temperature? See the 3rd link in my signature.

Have you been on the highway for any extended period of time, 15-20 miles?

Did you have the SAP & Evap monitors clear already?

You may also have a pending code holding up the monitor readiness for the O2 sensors/Cat monitor?

I replaced the 02's when I swapped the motor. And yes the Evap and sap already passed. And no CEL. I just looked at codes and pending codes p1190 and p1191 pop up but go away as soon as I start the vehicle up but then come back after diving it 15 ft, but no cel and yes I've done 55 foe about 30 miles. And engine temp is at 201-204 so it's normal it has a new thermostat... So frustrating so any ideas I'm going to log thus next dive and post my pids

You may have a Frankenmonster on your hands because of the engine swap??

The pending codes may be holding your final Readiness Monitors up.

There was a DME update for some of the early cars for these codes.

BUT, what engine, DME, intake, exhaust and so forth are on the car now?

If there is a DME update, then what one do you install and can you get a dealer to do it or are you going to have to do it??

You may want to look into post Cat O2 simulators?? There is a recent post about someone selling these.

Good call on checking pending code, jfoj!
Pending code will not allow monitors related to that system to be ready, O2 related in this case.

The engine is the m54b30 dme is Ms43
Intake is carbon fiber, Exhaust is Uuc Tse3 with headers and relocated cat. AA tuned the dme. Now before you say anything I had them All Pass last Month then I had to replace the post Cat 02 and it passed again.. Now I just finished Trans Swap gettag to the zf and sat for 3 days and for some reason they are saying incomplete all of the sudden. battery did die but these are the only 2 that cleared reset.. That doesn't make Sense
