I do not know, but any VW dealer does.  The 1.4 mm orifice is
slightly smaller than 1/16"; if you don't have a #54 drill handy you
could likely get away with 1/16.

I really don't know.  It's hard for me to understand why it's there at all.

>Also, that says 15mm, but the line is 3.5mm... How can that be?

Ah.  It says 0,15 mm, which is European for 0.15 mm (aka six
thousandths of an inch).  That's a very very small hole, half the
size of a #80 drill.  It might be possible to mold a bead of epoxy
around a greased strand of wire or maybe nylon monofilament.  But I
suggest seeing if VW has 'em before doing without or trying to build one.
