Wonder how many settings the BMW iDrive system has for programmable iWipe.
Why do I keep on thinking potty jokes when I say iWipe.
I just priced that relay in Oz - $110 plus 10% tax plus freight from Singapore (none in Australia).
Which city/area is the central point - equidistant from the Big 3? That's where I'm moving to!

Note that my manual and the actual relay board in my car use roman numerals and not arabics. I swear the only callout for the wiper relay is XIX which is the double-wide in the '20' position. And that doesn't match any of 928intl's diagrams from 77-95. Maybe I just can't read manuals...I'll check again tonight.
You need relay XIII.

You evidently can't read it right...

Here's the link to the 928 International relay chart.http://www.928intl.com/repair/Relay/earlyrelay.htm
I just got home and pulled out my workshop manual (7 volume red) and on page 90-3 the only reference to a wiper relay is XIX Intermittent Wiper. XX is the Intensive Cleaner Pump. If you look at the picture it shows two black-cased relays in XIX and XX. Well in my car I have a silver-cased double-wide covering both XIX and XX. According to the manual XIII is the Headlight beam power supply. And the 928 International diagram doesn't look like either one. At the bottom of the page is does say "Printed in Germany - II, 1979" which I guess means I have an older copy of the page?
I just want to plug in a new relay. I've changed clutches, exhausts, replaced master cylinders, and I'm getting ready to dive into the motor mounts. This can't be that hard....
You have an '83 so the intermittent wiper relay is not XIX or XX - however what it says for an '83 is wrong anyway... Whoever created this is an idiot...
The picture in this chart is a picture of a '85-'95 fuse panel with different numbers supposedly associated from a '78-'84 panel (...but...)
The problem with this is that the '85 fuse panel has more fuses (11 more) and more relays (4 more) than a '78-'84 panel... they chopped a bit out of the middle of the picture. But still the number assignments are completely screwed up. Its not quite clear for instance where relay XXII plugs in...?
Their relay "12" is actualy slots 1 & 2 their 1 & 2 are actually 3 & 4 - check against the manual page photo 90-3.
Jim B - you reading this?? - you guys should take this crap down before something bad happens....
See these charts instead https://www.928gt.com/default1.htm - under fuse relay charts by year (they are mostly correct - I know of only small details being wrong). It appears the panel diagram was copied from there (it also is an edited '85+ panel diagram & they didn't number the fuses for that reason... the relay # assignments are correct though...)
In your manuals look at the wiring diagrams on page 97-165 or 97-188.
The photo on 90-3 has the correct relay position # assignments for a '78-'84 but the table of relay function assignments below it is for a '79 - which you don't have... the way tye manuals were put together is that additional features & updates were just appended to the end - so there are amy things described that only apply to earlier models - you have to read the manuals backwards to be sure you have the right info....
Its still XIII - see 90-3

3.200.110 made by KAE (Kahler)
I was confused because this relay isn't set by turning on and off the delayed wiper. I tried to return it, but I'd already plugged it in. I even went online and found the relay's instructions, but still couldn't make it work. (KAE instructions)
Today I tried again, and found that you have to turn on the delayed mode first, then tap the squirter to set the delay.

If you turn off the delayed wiper, it will remember the delay you set, until you turn off the car. The default is ~6 seconds.
Set
1) Wiper stalk down
2) Squirt-tap, wiper cycles once
3) Wait number of desired seconds (up to 20)
4) Squirt-tap, wiper cycles once (unless it's still wiping from the last tap)
Reset
5) Squirt-tap, wiper cycles once
6) Wait number of desired seconds again
4) Squirt-tap, wiper cycles once
If you don't have the wiper stalk down in delayed mode, it will wipe 3-times as normal when you hit the squirter.
Only now after 15 years did I figure out the proper sequence for programming the 3.200.110 KAE relay

Program/reprogram sequence:
- Wiper stalk down
- Wiper cycles once
- Pull briefly
- Starts wipe
- During wipe cycle pull again
- Wiping cycle finishes and stops
- Wait desired delay time
- Pull stalk one time to set delay duration
- Wiper cycles one time and thenceforth at the programmed interval
My confusion and frustration was neglecting the second programming pull/wash during the wipe cycle.

I need to find the proper VW relay a la Alan, 3B0 955 531, where you set the interval by turning on and off the intermittent... which seems to be NLA.
Guess I will just get a new rheostat
