With the old cap, if I pressed down too hard while turning, I could feel it and I replaced the cap with the new style. I removed the gasket and put some oil under and on top of it, so it slides as it's turned. This seems to be the only BMW engine where this problem has existed for me. Must be a lot of oil splash right by the fill neck.
