Has the right driveshaft ever been changed in this van? If you have a replacement installed, this can be a problem.
The drive shaft for Mk6 has a short section with a splines, because the hub bearing is narrower than in the Mk7.
Some axle shaft replacement manufacturers do not want to produce two different ones. They produce a "universal" drive shaft with a slightly longer section with a splines.
After tightening the hub nut even with the correct torque, the hub can still sometimes move axially several mm - 2-3 mm. The solution is to add a second washer under the hub nut.
I had this problem twice, once the drive shaft was so long that the cap on the alloys (Ronal) was pushed out of the rim. I had to cut the drive shaft a few mm with an angle grinder. The noises during the ride were as described in the post.
