If the tiny o-ring is intact and the filter snugly fits in the oil filter housing, oil pressure and flow will be where it needs to be. I worked on a 328i that somehow had no center, discovered during an OFHG replacement. No codes but the filter was certainly doing little to nothing just sitting in there
