On most of the cars I've owned (in UK) there is a cover on the end of the arm that lifts up exposing a threaded shaft that the arm is attached to. Undo the retaining nut and ease up the wiper arm. It may be tight as it is on a spline. You may need to tap it with a soft mallet to free it, or use some WD40 or similar. When replacing be careful to line it up on the spline in the correct place or you may not get the correct sweep on the windscreen (as we say here).
To replace the rear wiper arm on an Audi A6 Quattro, begin by lifting the wiper arm away from the window. Locate the small retaining clip or nut at the base of the wiper arm; if it's a nut, use a socket wrench to remove it. Carefully pull the wiper arm straight off the spline, then position the new wiper arm over the spline and press it down firmly. Finally, secure it with the retaining clip or nut, and ensure the arm is properly aligned before lowering it back onto the window.
