Would anyone have personal knowledge on the procedures to replace a M104.990 engine camshaft position sensor?

Specifically, if just replacing the sensor, does it require resetting the air gap w/ the camshaft (which requires taking off the valve cover I believe?

Also, does the new camshaft position sensor have to be aligned w/ a particular setting with the camshaft when installing, or will replacing and using the factory supplied shim on the engine already be sufficient (provided the replacement sensor is exactly the same as the one being replaced)?

The camshaft position sensor has 2 5mm hex bolts holding it on the left front top of the engine, and is simply a magnetic sensor.

Thanks!
