In a nutshell... I have officially received word from KW conceding they are at fault. They are re-test-fitting the F30. They will not have a solution until at least a few weeks later. They finally apologized for my inconvenience and how I was treated. I have been offered a refund. They "assured" me that they never treat their customers like they treated me.
So for those considering the KW's, just wait a bit until the fix propagates through all the F30 kits.
NOTE: Obviously, I'm not going to go into too much details until my specific case is completely resolved. However, you can PM me if you like.
