Just a quick video showing how I was able to retract an electronic parking brake on a 2016 Audi Q5. I have been able to use this same method successfully on a few other cars as well.
This is basically just supplying a 12v power source directly to the parking brake motor after the electrical connector is removed. You may have to switch the wires to get it to go the correct direction (Explained in the video). Once the piston starts to spin, you can remove the power supply and use the screwdriver or small pry bar to push the piston all the way in. If you try to pry it in without powering the motor back in first, you will find that it will not move at all.
This is just a quick and easy DIY method that I have been able to use on electronic parking brakes.
Using a scan tool is the 'correct' way to retract the rear electronic parking brake, but I don't have one that has this function.
WARNING
**Attempt this method at your own risk**
**Do not turn on the car with the connector removed.**
**Do not put the power wires on the connector harness that goes to the computer.** (car side)
**Step on the brake pedal a few times until it feels firm after you put it all back together which will push the caliper piston back out where it should be before turning on the car. When doing this, don't press the pedal all the way to the floor which can damage the seals in the master cylinder.**
Thanks for watching!
