The intermittent wiper relays with adjustable delay in swipe make the
adjustment by being turned off from intermittent (move lever from first
notch up to the off position) for the length of desired delay (this varies
from relay to relay because some can be adjusted up to 20 seconds and some
for up to 30, I believe) and then being turned back on to intermittent
position of the lever.  I like the adjustment feature most in those
circumstances where the standard 5-second delay is too long, but full-on is
too quick so that you're running the wipers over an essentially dry
windshield.

If you do a Google search of Audifans.com for intermittent wiper relay, you
should find references to the VW part number that works for our cars.
