sorry to hear bud, on a car like that it should be repaired properly, not with filler, a new skin should of been fitted and the dent removed from the rear quarter, and the whole side of the car resprayed, and at a vw approved bodyshop, just incase you have problems in years to come with the 12 yrs anti corrosion warranty, this way vw know all about the cars previous repairs. i had an argument with an insurance assessor not long ago regarding a customers car, he wanted to repair this car with what he called white label parts (non genuine) my argument was the car had genuine parts fitted at the time of the accident so why not put the car to exactly how it was before hand, his reply was if they did he'd prefer to write the car off due to the extra cost.
