Just a guess but the handbrake cable might be too tight --- slacken it right back and pump the pedal to work the self adjusters, only then tighten the
cable only just enough that the handbrake lever will rise the number of clicks specified by Audi ----

Try disconnecting handbrake cable, remove caliper without disconnecting hose and wind back piston into caliper . With pads in place adjust piston to
give approx 4 thou clearance between disc and pad. Refit caliper and pump brakes . Repeat for other side ,reconnect and adjust handbrake cable. If you
still have problems caliper is faulty.

Older Audis/VWs had problems in this department. I think its some sort of ratcheting effect (mechanical piston not retracting properly after
application), and linked to corrosion in the mechanism. Recon calipers seem to be the only cure.
When I say older, I mean 80/90/Golf Mk2. If the design is the same, it could be this.
Removing/disconnecting cable is very good advice as a start point. And it costs you nothing.
