To be perfectly honest, it is easier the take the whole bumper off than just the lip.
They are very easy to remove.
4 screw in each wheel arch
8 screws underneath
4 screws to remove the grill
some mk5s have 2 screws in the front slam panel too. Some don't
then it just slides off
to take off the lip you still have to remove screws from the arches, all the ones underneath and then you have to unclip about 20 clips holding the lip to the bumper which are a beeehatch! Then to refit, it's just as problematic. Those clips can be quite stubborn
