Just like every Saturday night.........
Basically visually inspect and shove/pull everything. Everything should feel tight
Thanks for posting follow up for those looking for solutions in the future.Update: So checked everything I could think of and still nothing, so I put the car on jack stands (in my driveway, pointed in a safe direction) and ran the front wheels up to 70mph. Disabled, TC and ESC, I could feel xds doing a little bit of vibrating to get the wheels spinning the same speed, but once I got to around the car started to vibrate pretty good. More than I think XDS would cause. So I took the car to a shop to get the wheels rebalanced and to check my alignment (because an alignment check is way overdue).
Sure enough all of them were out of balance, with 3 of them being about 1 ounce out of balance and the left rear was out of balance by about 2-3 ounces. The tech also mentioned that on one of the rims the weights were put on in the center of the rim, and that they should be placed on the inside lip and the outside (as close as possible to the back of the spokes). Otherwise he said he went over all of my suspension and it all looked good, same with the alignment.
Took it for a drive and it feels a lot better now. On a smooth road at 75-80 uphill it doesn't vibrate like it did. Any vibrations left can probably be attributed to small imperfections in the road and the gti not being a luxury sedan. I need to take it on a longer drive to really see how much it fixed it, so if I find out it didn't fully fix it I'll update this thread.
Driving tires unbalanced for quite a while can of course cause them to wear in uneven manner, often causing them to cup. The uneven wear pattern caused by the bouncing can also wear out your shocks rather quickly.
