Yes, this one is a easy adjustment. If nothing is broken it's just to remove the inner fabric and adjust it. The sunroof is held by two small nuts on each side. You can't really miss them. Let me know if you need more specific info...
Don't know for sure if your sunroof is exactly the same but I guess so.
Haasman: You're right. It can be a bit tricky to slide the headliner out the way but if you do it carefully nothing will break. After that return sunroof to closed position and do the adjustment.
