Q Shift Knob Needs Rehab

[JEC]

Finally got to detail the interior of my new (to me) 1990 Q45 yesterday. With a little attention, everything looks new!

But, it appears that the spring in the shift knob has retired. I tried figure out how to take it off, but didn't want to break anything before finding out if there is a known procedure to remove/replace it. Any insights?

Also, is there a good looking aftermarket alternative out there? Mine is black to match the grey factory leather.

Thanks again,JEC
