Mercedes uses a "ball & socket shape " lug nut. As opposed to what the USA cars use, which is a "Cone shape" The contact area of the ball & socket lug nut is much greater than a Cone shape lug nut.
To break loose the ball and socket nut that is overly tight, you need to stretch the lug bolt to increase the length,, just a little... localized heat will do that... Shouldn't take a lot, you only need to grow the lug bolt portion a couple thousands of an inch to release the ball out of hard contact with the socket...
