Hey Siberian! I wish I had known! I ended up pulling a used one off Ebay.
So here's my story, and I'm sticking to it
I found a headlamp supplier on Ebay and I highly recommend him.
Just be sure to read and look closely at his ads - just see if it is the whole assembly or if it has parts taken off. It came boxed up better than factory. I only needed the "shell", all my electronics were good and I swapped them over. Check out the fixitmannn1 at A B PAINT AND BODY items - Get great deals on Headlight, Tail light items on eBay Stores!
on eBay Stores!
The other parts came NEW from Bryan at Volkswagen Parts | Genuine OEM Parts - VW Performance Accessories
Also highly recommended! Email Bryan, you can even just describe the part you want, he'll usually reply with a blown-up parts list like the one Treguese posted and ask which ones you need. Include your VIN.
I had to replace the headlamp mounting plate Treguese asked about. It's mounted with only 4 bolts/screws. Really simple, but you need to remove the bumper cover, which is also quite simple. I was shocked how easy the whole front bumper assembly come off! There's a PDF guide somewhere in clubtouareg that works well for removal. Have your star-drives ready!
The trick to the headlamp mount is, either bust your knuckles flying blind on the back bolts or have an insanely long 1/4 inch socket extension to reach from the front. The bolts have a small hex on the threaded end, there are some really deep trenches from the front that can reach back to tighten those screws. Just start by installing it loose and get the headlamp clipped into it. The front of the mount has two adjustable set screws to get the depth correct in the fender/hood. I installed the mount tight the first time, prowdly slid in the headlamp, and it stuck out, crooked, about an inch! Talk about a panic attack, how far out of whack was the front end???!! Nope, just get the headlamp clipped in and then dry fit the whole rig with your hands. Tighten the front set screws and the 2 front mounting bolts - and then the back ones just seem to kinda float, but tighten them til they're pulled in snug. It's plastic, so just snug enough to hold the headlamp.
Quick and easy-peasy. I'm thankful the treg didn't hit the column any harder and get into the steel parts of the front end. For me, last up is to get the bumper cover gouges filled and re-sprayed.
I don't know the differences between the front ends of the different years, but with a 1/2 model year change in headlamps, maybe not much There's other parts on the front clip that might need to be swapped, but I was struck dumb by how cheap the VW "collision" parts were. There are two guide brackets for each side. They hold the sides of the bumper, they might need to be swapped too. They're called the bumper side guide bracket (p/n 7L6 807 050 for the passenger side at least).
I don't mind if we switch this over to a bumper swap post, my mission is complete!
See you on the road!
