Front air spring o rings
 

Can anyone tell me the approximate position of the o rings in the front air spring? I have a kit that contains the rubber air bag and 8 o rings but no instructions as to where they go. I think I have figured out where the four small (approx 20mm) but would like to know about the 4 large o rings.

I do not know the answer to your question, but you can use BMW Parts Catalog to find the exploded parts diagrams for the parts used to build your car. You might find the o-rings shown on the diagrams. Input the last 7 digits of your VIN, then click Browse Parts. Find the suspension pages.
