My daughter's 2019 Jetta was the first car I've done brakes on with an electronic parking brake. Normally a dealer uses their software to tell the motor to retract. Or you buy a third party scan tool that has that function. Or you unbolt the electric motor from the caliper and turn the screw by hand. Or you disconnect the electrical connector and apply 12v to the appropriate contacts to retract. I went with the latter since I had a spare powersports battery handy. Still a pain in the ass, but cost me nothing.
What's funny is that once you get past that, VW actually made it easier to replace rotors by not needing to remove the caliper bracket - there's just enough room to tilt the rotor off the hub and sneak past the bracket. The cynic in me says they use the electronic parking brake to discourage DIY, then make the job itself easier for more profit to the dealers.
