The car should be repaired by a VW approved bodyshop as its only a year old . But then it does depend on who you are insured with and how you have dealt with it . My sons 2006 gti was hit in the side by a woman at a roundabout , we insisted it was repaired by a vw approved of our choice , which fortunately was one of their approved repairers anyway . This was last November when the car was 7 years old , it cost near on £6000 to repair ! If you had seen the damage it was not that much really but it is fantastic now and the paint is better than the other side which is still original .
If you can see where it has been repaired on a 1 year old car it should be redone and NO FILLER !
