Planning on doing my filter and oil change this weekend....I can definitely confirm this quote...my 328xi has the GM transmission....confirmed by the tag.
NOTE: you can also tell by the pan appearance. MY GM pan is aluminum and fairly flat on the bottom...no fins like the ZF.
Ill be starting a post as you have to do a few more things with the XI to get at the fill bolt...like removing a drive shaft.....
edit: My bad....you do not need to remove a drive shaft....see 328i and 328xi DIY elsewhere in this section.....
