This looks to me like a paint bonding problem. Im guessing the surface was not prepped correctly prior to the color coat being applied. American cars had a similar problem back in the 80s
Environmental laws forced manufacturers to use sub-standard paints and prep techniques.
I doubt your V-Dub falls into the manufacturing fault category though
Is it possible that this area of the car was re-painted at some point? If not, then I would check online for service bulletins regarding this problem. If it is indeed a fault in the manufacturing process, its very likely that Volkswagon will repair this for free.
In any case, this is not something the average car owner can repair his/herself. My recommendation? Trade this thing in for a Honda or Toyota.
