My knob came off while pulling very hard...but so did part of the boot clips and tue boot leather was ripped from the M Sport knob it was attached to. I installed a BMW performance shift knob. Now I'm dealing with the problem of the ripped boot. I saw that the M Sport shift knob had a yellow plastic attached eith clips to it. I have removed that clip and as soon as my wife comes home will see if I can work somethimg up (i live in a condo and my baby is sleeping). Will post puctures if it comes out successful...
