Yes. Remove the wiring plug and the two bolts that hold the electronic parking brake on from the rear of the calliper. You can then, with a socket or even your fingers, screw the handbrake spindle in clockwise, as far as it will go and then just push the piston back in the normal way. I have the tool to do it electronically but I just did it the way I described when I changed the pads and discs on our A3 because I’d lent the tool to a mate. You don’t need to reset anything, just put the handbrake on when you’re finished and it resets itself. You can do that with most epb's.
