Hi, sorry I don't sign on the forum much, the cars been sold but as I remember I got the part either directly from the dealers part dept or it was ordered from
http://www.bavauto.com/ As I remember it was probably bavauto just give them the part # they sell original parts. The shifter knob has to be pulled straight up, don't twist, if you did you probably broke a piece. It's really hard to pull off but it's straight up, no twisting. Sorry so late in replying.
