According to this site:
http://syntheticoil-europe.eu/141-g-052-171-a1-g-052-171-a2, it's a 70W-75 GL-4 gear oil.
Holy snoikies! I didn't know they came that thin. I'm thinking I'll just find a vendor that sells the genuine VW stuff so as not to lose sleep at night.

Manual Transmission Fluids (MTL) Fluids containing MTL Application Specific Additive Packages with GL-4 Ratings
Choosing a Manual Transmission fluid can be confusing.
Many times there is simply a specification referenced and no information about the viscosity of a fluid at 100C, where the oil viscosity is documented at the higher testing temperature.
What I recommend you do when looking for a replacement fluid is to determine the viscosity of the fluid at 100C either from the manufacturer's Product Data Sheet or from a New oil Analysis or VOA.
After knowing the viscosity at 100C (212F), one can then attempt to match up the fluid to one or more of those below:
A. The four MTL fluids closest to a Kinematic Viscosity of 6.1 (About the same viscosity as a DexronVI) or so are:
1. Castrol Syntrans FE 75W,
2. BMW (Pentosin) MTF-LT-3,
3. Honda MTII or MTF 2.
4. Ford FML-XT-11-QDC
B. The next higher viscosity MTL would be the 7.5 cSt versions (About the same viscosity as a DexronIII)
1. Royal Purple's Synchromax
2. Ravenol MTF-2
3. Honda MTF
4. VW part number G052512A2
5. GM Manual Transmission and Transfer Case Fluid
6. BMW (Pentosin) MTF-LT-1, 2
