Like a ... virgin!
I don't see how the filter can be removed without oil being spilled. Note to DIYers - wear a shirt you can toss. And, allow time to clean (rinse) dirty oil off the lower shield after the change.
When the board has tech issues, and you have to breakwhat you want to postinto small bits, it is less coherent than ideal. Of course, it is about me doing my "virgin" self oil change (first time I've done it on the M3).
