Not sure if he's right, but I guess since my M4 doesn't really seem to be lacking in power or sound, I'll take his word that even though my M4 was produced in July that it doesn't apply to me.

I wouldn't take a production date cutoff to gospel, BMW has been known to tip on one side to the other with parts or procedures during production. I would always start off by scanning for codes.
If once is experiencing erratic behavior with the electronics as some have been mentioning, it's a good place to start.
