Thanks for the info. I confirmed from another source that the part number was correct. You were kind enough to tell me I was plugging the right hole, so to speak. Plugged it all together and the intermittent wipers worked but were not programmable.

The fault then must then fall on the new relay itself, I says to meself. After looking closer, the relay I bought was marked KAE not Bosch but had a Bosch part no.

After some due diligence on a Saab or Audi board, which almost all use the same relay, one poster noted that there are a number of knock-offs and all work EXCEPT KAE, which is as that author noted and this author confirms - are pieces of sh&t.

New BOSCH relay from the VW dealer and all works according to plan.

Thank you again. Your post is one for the FAQs.
