@SpuGen I'm not really worried, it's just that if it's completely deflated it's not going to help add much height even if a 2x4 is under it.
After a second thought as well as with dhillon09's

help I think a scissor jack may do the job.....
the Fitment issue with the mk4 vw jack is that it's not a real scissor jack.. it's a "widdow maker" and attempts to fit and lift from the side and the slanted arm gets in the way.
I may try finding a scissor jack from a small car to see if it fits better. There's no upward arm to get in the way.
@Special K
That's a good question. Strange that VW supplies a jack given that there's no spare. I guess it's for safety/other potential issues. I've never used the OEM sealant so I'm guessing you don't need to be jacked up to use it.
