external bumper! Quick Question

Hi everyone, I have a question about my car,

There is a part in the back of my car that has fallen out, and I want to get a replacement but I don't even know what it/s called. I attached a picture, but its around the bumper area, and i believe it holds a black wire because now that's just hanging out. Thanks!

Also, if you can name that part, can you recommend where I can get this part?

Well, on my 2017 GTI, they call that the rear spoiler. It's actually two pieces, totalling $600. The diagram isn't very clear, but it looks like you might be missing only the one (rearmost) piece, which happens to be the most expensive one by far.

Or maybe you're missing both pieces. Again, the diagram isn't clear.

This information is on VW's web site. Any VW dealer can get you this. Any body shop can get you either this, or the cheap Chinese knockoff.

Was it stolen?


That is super weird.
