Wow, perfect, congratulation!

The two T20 screws you mentioned are connecting the motor with the hydraulic unit, right?

The hydraulic circle is a closed system, where no water can get in. If you remove the motor from the hydraulic unit in the middle, oil will run out and you should renew this o-ring. What about the hydraulic level in the reservoir on the left? You can take ZHM from Febi to fill it up, if required.

What about the current fault codes?

so i had water in the trunk again with the same roof problems i attemped to fix it by replicating what i did before and now the roof doesnt go down and i dont hear the motor running. i am getting a green light on the roof button but a red rooftop icon on the dash. the error code i am getting is 00a694. when i took the motor off the hydraulic unit some pins were beneath the o ring?. also would you happen to know what kind of oring it is so i can replace it.

Yes, there are some "pins" (6 or 7?) in a "wheel" on the hydraulic side of the pump, not on the motor's. None of them may be lost!

Very rarely source of an issue in our E89, as it sits on top of the windscreen.
