Fir a type 99 or 197 relay in place of original. Normally from a mk3 golf
When you wash the screen, it'll wipe just twice, and you'll have variable intermittent.
To use the Variable intermittent, flick the wiper stalk to wipe the screen once. Then wait for period of time "x" and put the stalk to intermittent setting. The intermittent delay between wipes will now be "x". That’s it. It’s a 5 min mod
Relays now harder to find than the old days as VAG have a newer way of doing it
