I don't know what VW may have known about the 2.1 rods but from what I've seen they started putting the extra oil warning system in their cars starting about the 1982 model year. It is called the Dynamic Oil Pressure Warning System. They eventually phased it into the full product line AFAIK, reaching the Vanagon production during 1985 (model year 1986). Waterboxers, inline 4 and 5, diesel and gas, turbo and non-turbos, all have it starting at some point.
