Typically there is no Junk yard that has them available. At least with pull your own yards, you have to have alerts set on your phone about arrivals and be the 1st one in because they don't last long.
Around here if it's a tdi that gets junked but runs it gets pulled into their shop and the whole thing comes out and then on to ebay it goes or however they sell complete tdi engines. Gas turbos too, they had a 1.8 bug that was tricked out in the yard and it said "not for sale, hold for shop" on the window. Sometimes one slips past inspection and makes it to the yard where head, turbo, n75s, mafs, fuel pumps, etc is gobbled up quickly.
I wanted complete clean doors with tint for my Jetta but all the places around here want to sell the skins, windows, etc as individual parts at a huge markup. No fing way I'm paying that just to have to put them back together, I'll wait to find a complete set of doors. One day me and Sambo, my partner in vw crime, made it to glissons upull and they had a black Jetta with perfect doors inside and out and tint,
$25 a door.
Spasms.
We couldn't find a socket to fit into the door jamb to unleash the treasure so had to leave it alone. Got a socket that would fit a week or so later and drove back to the upull expecting to drive away with our haul, we were smiling as we grabbed the tool boxes and headed towards the office. A guy popped his head out of the office and said sorry boys can't let you in the yard, why not we asked, he said they had a fire in the shop and the entire place was shut down. Then we noticed all the burnt cars and other debris in the back, but the fire was nowhere near the pile of vws they had way back on the lot so we kept hope alive. Something like 3 years later they open the upull up and we roll in overjoyed at the prospect of perfect doors for the Jetta. You know it was gone, their entire invo was changed. Moral of the story grab it quick or someone else will. Shoulda borrowed a torch.
