Well I think I got it...on this model the sleeve is actually one piece with the internal wiring of the transmission.


Must be nr. 10, 24367551877


Actually it could be only the outer O-rings, that BMW seems to have discontinued for some reason. But I guess it could be also the seal of each pin in the sleeve. Should be able to narrow it down once i disconnect the plug. If it's dry inside, it's the Outer O-rings, if it's full of oil... it's one of the connectors seals.

Anyway, don't know if I'm up to just swap out the outer o-rings and then have the single connector seals fail 1 year later
