According to RDL in post #118 here, the BMW TIS recommends the two little o-rings on the bottom of the oil-filter-housing stem to be replaced at EVERY oil change!

All I have is this screenshot ... so if you have the TIS - let us know what it actually says.
Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
