The plastic is simply split loom. Common on vehicles to protect the harness and make things neater than having a mass of wires hanging loose. Many auto parts stores have it. If you want to be sure of the size and yours is damaged, just take a small piece with you to get the replacement material. If you want it to match the original stuff you will likely need to go to a VW dealer or visit a salvage yard and strip some off to get the same style, otherwise the common aftermarket stuff works fine. As for which harness it is. In front of the radiator is likely lighting or air bag related. If you post a few of the wire colors in it I could probably tell you for sure.
