Old thread, but relevant.
I was reading about the factory optional jack points (not the pinch welds) on the 2015 Golf wagon and where to get them and what to get.. plenty of info out there, some of it confusing, some incomplete.
The kit from ECS at start of this thread is sort of factory but not how VW would have done it, and it cost $90.
This thread has the proper and complete parts list and details covered pretty well.

This one has a few pictures and confirms some of the part numbers in other thread, but not a complete parts list or info.

From my research you don't need the ECS kit.
Alternately, all the other factory parts if bought from ECS is over $200, so I looked elsewhere.
Ordered the parts from
http://e-acca.com, and don't know if they'll deliver or be right, I've never bought from them before. They are supposed to be genuine VW and they are cheap..
$87 for everything, delivered fedex in 2-5 days. Worth a try.
This is what I ordered, same as explained in first thread linked above
Round rubber bungs for front points, order 2. (presumably same as ones come in the ECS kit) New part number ends with "B"
8V0804631B
Square pads for rear, order 2.
8V0802847A
Trim pieces for front, one left one right.
8V0825271
8V0825272
Jack sockets for front, one left one right. (these larger ones cover holes in new trim pieces instead of the little plastic pieces in the ECS kit)
8V0802845
8V0802846
If these parts work like I think they should it'll be cleaner and cheaper than buying the above mentioned kit from ECS and using a hole-saw on original front trim pieces. And includes the larger rear blocks instead of little round rubber ones.
Also a lot cheaper than ordering the same proper VW parts from ECS.
Hope it works out and it helps others.
