<i>I installed this relay back in the fall and just remembered how nice it was last night when it was sprinkling. I set it for about a 10-15 second delay and didn't have to mess with the wipers at all. The information below is copied directly from 20v.org</i>

*****************************

<b>Variable Intermittent Wiper</b>
The following explains how to install a 'programmable' intermittent relay which will give a intermittent time interval from 2 to 45 seconds. The time interval is programmed using the wiper stalk switch.

The relay is Bosch P/N 0 986 335 058. It should cost between $30 and $40 from any one of the following:

* Automotive Performance Systems (800-423-3623)
* Wolf Sport (800-342-8669)
* VW or Audi dealers -- VAG P/N 1HM 955 531 A
The "A" is the important part, but this part has been superceded, so when you ask for it, they may try to give you a part that ends with "B", "C", etc. The "B" part does work, the "C" does NOT!

<b>Installation:</b> <font color="red"><i>see update below</i></font>
This relay takes the place of the relay in position #9 in the main fuse box under the hood. The relay to remove is white and has a large 271 printed on the top. Its part number on the side was 443 955 531. Remove this and replace it with the 'programmable' relay.

<b>Operation:</b>

1. Turn the wiper switch to the intermittent position then turn it to off. The wiper will wipe once.
2. When you need the wiper to wipe again, you place the wiper switch to intermittent and leave it there. It will remember the time interval and repeat the wipe at this interval.
3. To change the interval, just turn to off (wiper will wipe) and then turn back to intermittent position to set the new time interval.
4. The relay is reset to a 6 second default interval when ignition is turned off.

Yeah, I have one on the S4. Nice upgrade. I bought it from a dealer for ~$40.

Nice...I'll definately be doing this ASAP.

Audi Logic

I wonder why Audi didn't supply it in the A6's.
seems that VW was ahead of the curve back then..
starting in 95 VW had programmable wiper relay, one touch up and down and turn key open and close for all windows, audi caught up in 97.

Where is the relay located on 95/96 VW jetta? I am going to the junk yard and see if I can find one tomorrow.

I'm about 10% sure the white number on the relay was 99... You'll probably want to write down the full part number before you go!
