Yes, at least until 1990.

The 2WDs were built in Hannover, the 4WDs in Graz, Austria.

The VIN: VWV ZZZ 25 Z HG 000001
                |         |       |    |   |      |serial number
                |         |       |    |   |year and location
                |         |       |    |filling
                |         |       | Type of van
                |         | filling, used in the U.S., I think
                |VW

The HG is the important part:

first letter: A-N describes the year (A:1980, B:1981...N:1992)
second letter: G: Graz, H:Hannover

So the VIN above describes a �87 Vanagon built in Graz. It is a Syncro.
The same VIN with "HH" would describe a 2WD, because it was built in
Hannover.
