Wiper delay

[Tailwind]

I don't have the pot on dash, but have a rain sensor. The instructions in the UM are not clear, but driving yesterday , I put the stalk in position 3 but the wipers never came on.
Somebody please enlighten me.



TIA

I thought the speed dial was required with the rain sensor system. Are you sure it's OEM?

Edit: I remember now that yours is not OEM or the Porsche retrofit kit. That unit would have come with its own relay. You'll need to find the instructions for it and maybe check the wiring.
Most aftermarket kits work in the intermittent position (3) and will only come on when rain is detected. Was it raining or did you sprinkle some water on the windshield?

I believe you're right. There is a German company that made those Xanonex - Regensensoren
Mine is obviously an aftermarket, as the sensor is taped to the windshield:

I tested it by spraying water on the windshield and it did wipe, but needed more than a little water.
When it rained, the thing did not seem to work. I'm still not clear on how to trigger it.
What I want is to be able to set the delay, and am considering the VW relay route with wiper stalk 0-3-0-wait-3 scheme. I'd rather control the intermittent time.

btw - I can press up from 0 to 1 (not detent) and get one wipe. I didn't find mention of this in the OM.
