I thought there was a thread on the ID.4, but I don't see one. We have had ours for a couple of weeks now, and we have about 1200 miles on it. The trailer tow bar and wiring socket came today from etrailer.com. The wiring works easily - VW sells the 7-pin socket for $57. The same piece sells at etrailer for $12.04. We also got a 7-pin to 4-pin adapter, made by the same company, and it has a catch on it, that holds it in place when it is plugged in.
We got a tow bar with a 3 1/4" drop, that is the right height for our 5x8 utility trailer. The only snag came from an unexpected piece - the shear pin that retains the tow bar is too short to reach through the receiver, because it is designed with a steel plate on each side, that extend down to attach the safety chains. I solved it, by grinding into the shoulder of the 'J' shaped pin, so it can extend through about 1/2" more, and the Clovis pin can be inserted in the hole.
Here's the parts we got:
7-pin socket: https://www.etrailer.com/Wiring/Pollak/PK11893.html It says it is not confirmed to fit an ID.4 - but I am confirming it fits exactly, because it is the exact same part made by the same company, that VW sells.
4-pin adapter: https://www.etrailer.com/Wiring/Pollak/PK12716.html The tab on the side of the adapter holds it in place with the spring loaded cover of the socket.
This is the draw bar: https://www.etrailer.com/Trailer-Hitch-Ball-Mount/Curt/C45017.html It is under the 7" maximum length that VW specifies. There are a number of tow bars that are a fraction longer than 7", and I can't imagine they will not work very well, but I figured staying under the max is good.
This is the pin that is too short, so if you can find a 1/2" x 2 1/2" (or a bit longer), then that is easier: https://www.etrailer.com/Hitch-Pins-and-Clips/Curt/C21410.html
We got a 1 7/8" ball: https://www.etrailer.com/Trailer-Hitch-Ball/Curt/C40001.html A 2" ball will also fit, if that is what you need.
Modified Shear Pin
The receiver is about 1/2" wider than a typical 1 1/4" receiver, so you either need to find a...
The pin is still just as strong in shear as it was - the bend is still much stronger than the Clovis pin on the other end. All they are doing is holding the shear pin in place.
