Well I was looking at the parts manual and I realized that all the diagrams show the oil cooler lines to be the same on the 616 and 617 engines. My daughters 240D has both connections on the bottom of the cooler. Does anyone else have this setup?
I wonder if it is a special "setup" done by the indy who worked on the car for the previous owners.
