Hello all
I have a wayward rear wiper on my touring and recently bought a replacement interval relay for it from the wonderful ebay. My problem is that I don't actually know where this thing lives on the car. It's a Siemens 1 385 901 12V part called a Wisch-Wasch-Intervall Steuergerat. Lovely. I don't even know if this will fix the problem but might as well give it a go. If any of you fine folk know where it fits I would be most grateful for the info. Thanks for now.

No, it's a 6 pin relay type box which looks like it should go either somewhere in the rear side panels or behind the glovebox. It may not even fix the problem but I though it was worth a go for a fiver. I'll take a look at the microswitch though seeing as you mentioned it. Thanks for responding anyway. TTFN

It's usually in the left hand side panel where the feedpipe runs for the rear washer bottle, back towards the tailgate, you should be able to find the wiper loom and it's part of that.
The way to test the micro switch on the motor is to use a multimeter to check it in the open and closed position. Mine wasn't giving a reading so I knew it was the micro switch. I would guess that it is a strong possibility it is this switch. Either get another motor, (try pm to SPADGE) or replace the switch, it's quite easy.
You will need to remove the motor and take it apart, careful when you remove the water hose not to snap the plastic connector. X6 screws to the rear to remove. Melt the solder on the micro switch on the outside and remove all the solder so you can push through the switch and remove it. Zimmerbimmer in the parts department will supply a new one. Then just solder in another switch.
Thanks to Chris W for this knowledge.
