if they start to worm vw will replace them, my wheels wormed up looked sh!t really ruined the look of the car first vw where going to replace all 4 wheels under warranty then they would only refurb them then they knocked the claim wayne kerrs, so dealer sorted them through L**SONS 3 weeks later the worms are back im now driving a chevy tacuma 1.6 whilst my car is on the ramp (nice) apparently the wheels cant be refurbed more than twice as there hollow going black next time, since june its been off the road 10 weeks i HATE this car where to go to next.
