Anyone else had this issue, the seal inside the van that the door would close against, has started to come away as in the pic, and there is a bit of corrosion where the water has ingressed, you can see how this has happened, whoever used the van before has stepped on the seal when getting in and out of the van, not so bothered about the seal as I can repair that with a bit of blak silicon, but the corrosion is another matter, the van is only 8 months old, should I take it back to VW, it’s on the driver side , passenger side is ok
