My E92 has been leaking from the drain plug. I have re-seated it a few times with out much luck so I bought a new one (control sleeve and adjustment plug #2/3 at www.realoem.com/bmw/enUS/showparts).
My question is how do you get the plug and sleeve out? It has a 'nut' on the outside, but looks like it is a key-way with slots and tabs. Is there a trick to lining up the keyway?
Thanks in advance.
