The car is 2012 Skoda Octavia(1Z) and the tailgate does not close smoothly. It went to the service for another problem in the trunk then this happened. Normally it closes from very low height properly and silently. Now tailgate does not close at the same height so I need to drop it from higher height. It makes too much sound and different noises that comes from glass and other parts.
I assume adjusting bottom latch position that may solve the problem but what could be the reason of the problem?
After Investigation Edit: I checked the 'gate thoroughly today and realised that it is tilted. I guess it explains the noises and not closing. So the problem is tailgate stands closer to the left. There is small gap between left panel and gate and huge gap(60mm or even 1cm) between gate and right body panel. In this situation how can I adjust it?
