Warranty success! Took my car to VW garage in St Albans. They referred me to the body shop who initially took the pictures of my front arches. Couple weeks later, got a call from a woman at Lancaster VW in St Albans. Needed to come in for a couple more photos.
Apparently it didn't quality for the Anti Corrosion warranty as the perforation wasn't from the inside and was apparently forming from the outside. But the woman at VW (Glenda Gurney) helped me out and managed to get 50% paid by VW factory and 50% paid by VW customer care. So booked my car to get some brand new wings for the 1st week of Sept, free of charge. Getting a courtesy car too. Win all round!
