As a side note;  the schematic parts drawing looks like the cup side goes toward motor, not toward spring.

The new style piston and its orientation that we are discussing are not illustrated in that drawing, Atabeach. That is the old-style assembly. The items within the red rectangle have been replaced by the single piston unit.

Nicely documented, Laitch… the puck is actually 3 pieces!…. the untrained eye ( mine ) quickly glanced and saw the recess in photo as going TOWARD engine. So when the prior owner replaced the boot it was done with the hole toward the spring…I did that too… Thankfully I’m still waiting on stainless fasteners and will install correctly…ughhhh

It takes some practice to really see what you're looking at in these fiche diagrams, but the illustrated instructions in a MaxBMW-style fiche give a heads-up to many changes and can be helpful. You're likely to get the hang of it. BMW tends to update some parts and systems during a production run sometime making repair or maintenance an adventure.

The old-style assembly is three pieces. The new-style is a single molded piece.

Just saw this, that ramp looks like a lead in to a tragic/hilarious YouTube video
