I swapped out all the fuses in the fuse block with new ones, and went through some of the connections in the engine compartment with dielectric grease. Then I opened up the CAN box to have a look at my EACM again, because my dealer tried to tell me that it was a Bosch part, not a VDO part. Here's a picture of my EACM, VDO origin, version K9, manufacture date 10th week of 1991. I'm going for a drive tonight. Let's see if the gremlins are still on board!
