I talked to one of the techs about this about a year ago. He said the upper A arm and fore (lower) link don't require removing the battery and the aft (lower) link does require removing the battery. I asked them to replace those as owner pays, and they said they would, but returned the car without doing it and didn't charge me. They did find play in the sway bar links and replaced those under warranty. Strange days... And FWIW, the wheel liner is pretty easy to remove - much easier than on my MINI Cooper S.
