Just did this on my 328i and i also used zip ties. I only pried off the end of the U wire clip closest to the actuator and tied it down. dnt know if im supposed to unplug the actual wire thats connected on there also but for future references tying the clip in the up position opens the valve..correct me if im wrong
or share your thoughts
make sure its real tight so it doesnt rattle. haven't gone for a test drive yet, but i will tomorrow n will be checking for faults/misc concerns and f/u if needed.
