If you search the VW part number on the side of the black plastic plug, you can usually locate the plug (female) and a suitable mating male connector on AliExpress. The crimp tool to properly crimp the wires is available as well, for fairly cheap.
I recently had to find the two pin connectors used on blind spot monitoring wires, and got them for under $12 for five of each both male, female and the appropriate pins (with shipping).
