Omg I've been looking for this, someone told me about the green film but didn't know the name of it. Anyway I had to replace my timing chains and tensioners, oil pump and chain all new gears. Got it back together and can't get rid of the cam position sensor code. Now I will check those wheels, if I'm not mistaken they are pressed into the camshafts I don't think you can get just the magnetic wheel.
Thanks for this great video! Using the reference waveforms from the first seconds of the video, I found out which camshaft was bad, by comparing to the waveforms on my car.
