can anyone please tell me how hard/ easy it is to adjust the arms on the front wiper arms?

I recently bought a brand new drivers side OEM wiper blade and when i put it on....... it started to scrape some of the paint off from the front A-pillar.. just on the edge, and you can hear it touching too..
last time i changed them they never had that problem...

I went to the dealer and said that it was because the wiper arm needed to be adjusted, but they would charge $60 + tax........

can anyone tell me how to adjust it on the mkv jetta/ rabbits?

i cant find anything on the forums...... any help would be much appreciated..

thank you!!
