Any of your Mk6 GTI's have a leaking rear washer? I have already brought mine to the workshop more than a month back to get it fixed but sadly it just got a bit worse. Based on two months of obsevations, the leak seems to occur during enthusiastic driving and manifests itself by streaks of washer fluid on the rear window. I'm afraid some of the paint work at the bootlid has already been slightly affected. I will ring the dealer again to get the thing fixed but really do not want to drive to the workshop as it is inconveniently located. I am thinking of waiting till first service (around 6-8 months away) to get it fixed (again). What would you guys do? Think it's serious?
