Last time I drove my Audi, the rear curtain wouldn't go up and made strange noises. I suspect dust or small debris got stuck in the tracks, blocking the movement. This thing operates with a small motor and gear system - sometimes after prolonged use the motor overheats and burns out, or the gears wear flat, causing that clicking sound. It could also be loose wiring causing poor contact and unstable power supply. I recommend first trying to manually push it to see if it moves. If not, take it apart to clean the track dirt and lubricate with some WD-40, but don't force it to avoid breaking the wires. Audis have lots of electronic components - leaving it unfixed might affect other systems like window switches. Safety first, better get it checked at a professional shop.
