Valvetronic removal/installation help

Hi,
I need to change the valvetronic motor gasket on a 2007 X3 3.0L si.
I see the three torx bolts that need to be removed, however, I have a few questions.

Once I remove the 3 bolts, I believe I need to use a small torx bolt in the middle of valvetronic motor turning counterclockwise to losen it from the engine. Is this correct?

Once I get the valvetronic off, how do I re-install it? Do I simply push it in and put back the thre bolts? Do I need to do anything with the center torx bolt?

How do I get the valvetronic motor to align with the engine once it has been reinstalled?

I have no experience with these engines and don't want to mess it up. Any guidance would be appreciated. Also, I don't have any fault codes right now - do I need to do anything with the computer once I have reinstalled the valvetronic motor?

Thanks!

Under step 15, this DIY talks about removal of valvetronic. I have not done it myself so don't know much about it.

When I changed the valvetronic gasket I simply removed the screws holding it in place and took the piece out. Once I had it all cleaned up I put it back together without a problem.

When I changed mine, I just unloosened the 3 torx, it sprang out a bit. I did nothing else after this.

I can't find the link at the moment where I found this, but it is supposed to reset it self when the key is turned prior to each start. If you engine runs rough, reset your computer as desribed in the link above.

This is one of the things that looks difficult, but is really easy.
