I made a text file with all the information about this relay when I was looking for one. I'll paste it here, below. I finally bought mine from eBay...paid about $20 with shipping. You'll have to be deligent to find one there as it's a timing thing (sound familiar? I'm the same guy who posted on Swedespeed). Just don't buy a KAE one. They are a POS.
VW part# 3B0-955-531 (has a "99" on the top and is black)
The programmable unit: (VW revised part #) 357 955 531 or
the new number 1HM 955 531B for under US$40.
Note, APS sells these control units for about 10US$ less. The APS part
number is: 25-955 531
The Bosch part number is 0 986 335 058
VW charge £35 (part number 357 955 531). They have used at least four manufacturers, Doduco, Beru, Kostal and Bosch. Doduco, German made, was fitted on the 94 Golf's and uses an SGS Thomson chip. I haven't found a UK agent. Beru (part number 0 900 301 082), also German, is on later Golf's and uses the same chip in a half height relay case. Beru tell me they no longer make this part. The Kostal (377 955 531) is Brazilian with a Motorola chip. The German car co (www.germancarcompany.co.uk) has supplied both the Kostal and the Beru for about £15 each. The surface mount construction of the Beru is preferred. I haven't see a Bosch (part number 0 986 335 058), but they tell me it's available and retails for £20. (note, copied from a Brit.)
Variable Intermittent Wiper
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The "A" is the important part, but this part has been superceded, so when you ask for it, they may try to give you a part that ends with "B", "C", etc.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!
Installation:
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.
Operation:
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.

97 Passat GLX has this relay OEM...not sure about other Volkswagen's, but some Golf's apparently do too.
