So either you are wrong, the BMW docs are wrong and I have an N26, or they have changed the oil pan on the N20. Which do you suppose it is (seriously)?
I did a bit more research, and I think I've found the explanation. From browsing the RealOEM parts database it appears that all F30 328i N20's and N26's have a plastic oil pan (and plastic plug), the F30 328iX N20 and N26 have metal oil pans (and metal plug). I was assuming it was an N20 vs N26 issue, when in reality it's a 328i vs 328iX issue.
