Something strange here... I've a 2008 e90 335xi (sedan) sport package, I've unplugged the actuator cable, and I've not seen any sound difference or so. Then I got the JB4 G5, so I plugged back the actuator cable, and set the CANflap option using menu 4 option 5 (force it open all time). Again, I've not seen any sound difference or so. Any idea why? valve blocked? Thanks.
