Just had my two front fenders replaced under the rust warranty. The issue is very widespread at the top of the wheel arch, it’s largly due to the foam insulation behind trapping salt and debris, and more TDi prone apparently. I noticed the paint peeling back when my car was on a friends lift a few months ago. I then saw the rust creeping under the paint at a certain angle, I pulled a bit of the paint off, it would have been off once the snow started anyways. I filled out the form on the VW site and got my appointment. The lady took one look and said it’s automatically covered in this area due to a service bulletin and high volume of claims in this area. She did pics and documented it, but, said it’s a formality and called their body shop of choice and booked me a time that day and had the fenders ordered. It was a four week wait only due to the Christmas and New Years holidays. I only lost my car for 2 days. I don’t have a pic of the rust, but, maybe 2 inches wide and 1/2 an inch tall at the top of each arch. Only surface rust as well, no perforation whatsoever.
