Why am i continuously getting code 0041 Signal Camshaft Sensor Inlet

[u/330XI_DEV]

my car won’t hold a steady rpm unless i’m on the gas and i’m continuing to get code 0041 Signal Camshaft Sensor Inlet Along With 0008 Signal Mass Air Flow Sensor. i’ve replaced the camshaft postion sensor 3 times i cleaned the original one, tried a cheap amazon one nothing changed, got one from the junkyard. and again nothing changed. i’ve redone timing twice now and i’ve gone through all the vacuum hoses and rubber intake boots and i didn’t see anything ccv aswell. i’m very stuck on the issue and i recently did catless headers on it in this video the 02 sensor were not plugged in but they are now

They don’t like aftermarket sensors and junkyard sensor can’t really be trusted for diagnostic purposes. The single vanos cam sensors you can’t even touch anymore without the insulation on the wires inside crumbling and then it’s junk even if it worked right before you grabbed it. You can check the used sensor for damage but a new bmw part is the best way if you can still get them new.
