I have had the same problem. I tried looking for the part again and it doesn't seem like it is made anymore. All of the bmw sites show the new cylinder shaped part that everyone is talking about....
I think I found the old part number: 41612992997
Unfortunately, that does not come up with any results. Instead you get redirected to the new part that others have posted: 51237162448

It is super annoying but I guess I'll have to replace what is left of the pyramid shaped stoppers with these and hope the hood closes properly
