Are you able to check for codes with a VAGCOM or get them from a dealership / independant shop?

Even if there isn't a CEL, there should be some codes that may help identify the problem.

Default any success?

I am starting to have the same issues. But, mine may be due to an out of wack O2 sensor, but that is being replaced this weekend.
