HI Karl,
      Hey this switch is real easy to replace. Only 1 alien
key holds it in. You can see it by looking straight down. You
will see 2, 1 is a cam arrangment used to precision adjust it,
the other holds the thing in.  There is a replacement from
VW that you need to get that undates these to a better design.
