Hi, congrats on the new car, I had the same problem with my knob asked on here but i dont think i pulled the secret hand shake off! I finally got one after months of searching. Richwood do one, a small ball type, very neat and fits snug with a little grub screw. Solid alloy type, very cold in the morings! I got the silver colour, but the dark grey looks smart. In my opinion, the best aftermarket knob for the 220. Hope this helps.
PS i found it new on ebay, if you need the seller msg me and i'll look it up. Mike
