both my GTI 6 hutch struts have gone dead and the hutch cannot stay up. I went to the dealer, they refused to change them even though car is still within warranty, they said I wasn't servicing the car at one of the authorized dealers therefore warranty is void. Is this true even though the broken/deficient part is not an engine part? I mean, noone touches the hutch struts no matter where you service your car. Ta.
