Step 6: Using a filter housing tool you've had since the early 90s..... or a BMW approved one
..... remove the filter housing and filter assembly.
Note: whatever you use, it needs to be a "top mount" style oil filter wrench. There is no access to turn from the side.
All vehicles are different. This one will have a bit of "splash out" when you remove the filter housing. It's unavoidable. No big deal, Just be prepared for it.
