New to the form, was working on my 2012 535i? that I have had for a few weeks . I see this threaded hole by the oil filter. Is there supposed to be a sensor or something that needs to be there? I'm getting a Drivetrain malfunction error. The codes are 123001 120308,120408. Thanks

Not having a 535i hard to say… With engine running is there any suction or pressure there ? Could very well be as e4603 stated a funky hoisting point.
