You absolutely can get the oxygen sensors to complete for inspection. You have to flash to MHD V10 Stage 0 tune and select your necessary options (catless, tmap ect.). Then do a proper drive cycle. I just did this this week and everything set except catalyst. It took a few days for Evaporative system to set. Need to be under 3/4 tank of gas.

I have been dealing with the same issue of lunging at steady speeds. My 08 335 is completely stock with no tunes. I have replaced the coils and plugs and just completed a walnut blast of the intake valves. Ran great for about 20 minutes after the walnut blast and now is back to lunging. So far I am not getting any codes to show up. Any ideas would be greatly appreciated. I am new to the BMW family.

I’ve had the same issue on my ’06 E92 335i 6MT with N54 until today. The car counts 162k km now, so roughly 100k miles.
I drove MHD Stage 1 V7 with 45 % wastegate rattlefix, MT shift bog fix and stock DP selected only with upgraded charge pipe since 2019 without any single creeping issue until last month.
Recently I decided to upgrade my FMIC and afterwards everything went just as normal. Then I flashed the current version of MHD, long flash, but Stage 1+ Map V7.1. Same as before regarding waste gate rattlefix etc.
And then came the jerking/oscillating behavior around 1500 to 2100 rpm with nearly no load or 10-20 % pedal. Just slightly… but it was driving me nuts. What had changed since the day before? Only the new version of MHD – no doubt. And the issue was not there.

So I did (before) and tried physically
o Intake valves cleaned ~30.000 km
o Checked the vacuum hoses which ALL had been changed in 2018 – still OK
o Pressure of LPFP and HPFP OK
o Also no fuel leaking, no cracks, nothing
o Injectors were changed before I bought the car in 2016… but index? INPA says all injectors are working fine and I don’t have (had) any other issue than that damn jerking
o Spark Plugs NGK 95770 0.6 mm recently changed (500 km…)
o Cleaned Vanos solenoids
o Coil packs changed now to Delphi
o Changed TMAP sensor now to Delphi
o Changed low pressure fuel sensor to Bosch (new version + adapter)
o Inspected intake manifold, valve cover, searching for air leaks… nothing

And I tried in MHD
o Logging brought same oscillating curves as already shown in the thread
o Then flashed V6, V8, V9, V10… same crap
o Waste gate rattlefix in 5 % steps up to 100 %
o Aftermarket DP selected for the oscillation fix
o Complete removal of MHD* + new flash
o Reset of all adaptions via MHD
o Reset of all adaptions via ISTA-D
o … perhaps a lot more I can’t remember
*Complete removal of MHD also seemed to solve the issue, but an N54 completely stock without tune? Ah.. c’mon.

EDIT:

I renewed the vanos solenoids and was truly thinking the error would have been gone, because I couldn't feel it anymore. But... at the same time I resetted the adaptions again. Now it came back in the last days. Slowly... tenderly :-D. The only way to get rid of it at the moment: Removing MHD. The old V7.0 Stage 1 map was simply amazing and worked 5 years without any issue... directly after flashing to new MHD+ and Stage 1+ with long flash the issues were there... no matter which map, which stage... I keep on working for fixing this crap :'(
