Loose door handles in cabin

Common issue! Poor design really.

The outer half of the handle clips off, gently lever the bottom of the outer shell and push up, it will pop off with some teasing. There is a torx head screw in the top of the inner part of the handle, tighten that, but don't go mad! Try a little tiger seal or similar along the mating edges when you reassemble, it still wont be brilliant, but it's improved the feel of mine no end.
