Yes, there are industrial versions of the 1.9TD as well as other VW
diesel and gas engines. Many people have used an industrial 1.9TD in a
Vanagon. There are issues with some industrial versions of the diesel
injection pumps but the engines are about 95% the same as car versions.
Engine code AAZ refers to a car version 1.9TD, specifically. Industrial
versions have a different 3 letter code.
