Okay, here's one of those irritating things that I have found
occassionally with VW parts.

VW almost always includes the part number on the part itself. In my
case, the fuse/relay holder on my 86 Vanagon has the part number 171
941 813 D. Very easily read.

Except that's not the part you have to order to get a replacement.
You have to order 171 941 821 D.

In previous cases, this wasn't a matter of a part being superceded,
because what got delivered was still labeled with the other part
number. We'll see, if in this case, the part I order comes labeled
with the ordered part number, or the embedded part number....
