The way I understand Autohold works on my Tiguan is that when the brake is pressed the ABS pump pressure keeps the brakes applied. The engine has to be running to work the pump. After a while to prevent the pump overheating the rear brake motors take over from ABS pressure and apply the rear brakes also when the engine is switched off. Does the X1 have motors on the rear calipers?
