I decided to do the install of the trailer hitch module and mount today. It's only about an hour project, and from all aspects, it's just like the install on our previous 2010 Tiguan.
Problem is ... one of the bolts that holds up the receiver will not thread into the nut. I can use my fingers to thread three of them in, but the last one (drivers side front), will not thread in with any of the 4 bolts. It feels like it's a bad nut. Doesn't seem to be crooked, although that could be part of it.
So, this is certainly a problem. Guess it's a trip down to the dealer tomorrow to see how they want to handle it. From looking underneath, you can't get to the nut at all, and its likely spot welded in too. That means taking the rear bumper cover - and who knows what else - off. Maybe they can rethread it if they have a long enough rethreading tool ... but for sure, I am not going to try and force the bolt into place. I am sure it will get locked in place well before it tightens, and then its my problem.
Certainly this isn't a dealer fault, but VW will have to come up with a fix for me. I'm not too thrilled about the rear covers coming off on a car that we haven't even put 40 miles on yet.
