Hello everyone, my 2012 Touraeg v6 battery died on me so I replaced it with one from the dealer. Everything works except for the automatic trunk liftgate. doesn't matter whether I use the button on the driver door, remote ctrl or the tailgate itself... it will unlatch/latch the lock but wont open/close the door. I have to manually raised the door to open or push it down to the door. No fault codes. Any idea what might cause this after battery was replaced? I did not have this issue prior to the battery failure. Any feedback is appreciated..
