When activating the handbrake afterwards you can hear that the two motors run som extra time to reach the pads again.

There is no need for the special tool :-)

I can now confirm this as well. I used the 12V battery pack from my impact driver and connected it directly to the two terminals on the EPB (after having unplugged the EPB, of course). The first time I attempted it I had it backwards so it actually put the EPB on. I then was unable to take it off without turning the car back on and turning them off normally. Once I did this I was able to go back and reverse the poles of my two connections and the EPRB rewound without issue. You'll know you have it right when you hear the brake rewind for an extended period of time...say 5sec. As Peter indicated (above) no need for a special tool here nor is there a need to take the EPB apart. This is good news given the recommendation by VIDA to replace the seals on the EPB each time you open it up!
