another victim of Rain X here. I finally got around to cleaning the sensor when I did my oil change this past weekend. Sorry, I forgot to take pictures, but overall it's a fairly easy job.

After buying Rain X 2 in 1 fluid and filling our Tiguan's reservoir up for a trip my wife took, she came back with the warning light on to refill the :banghead:washer tank. It wasn't empty but I topped it up and the light would still not go out.
Quick fix for poor souls who suffered from evil Rain-X. Go to nearest pharmacy, buy two 22 oz bottles of 91% isopropyl rubbing alcohol. Empty your washer fluid reservoir by constantly running the pump for 2 min. Pour both bottles of rubbing alcohol into reservoir.
The rain_x fluid will kill the sensor. Take it out and use brake clean. It should be good after a good cleaning. As long as the contacts on the sensor itself are clean it should be good to go.
In my TT, I had been using orange colored Rain-X washer fluid in my car for nearly 2 years... It finally reached critical mass in my car at the beginning of September. Yellow fill washer fluid light has been on for weeks despite the tank being full.
Confirmed: Orange RainX is the problem I called Rainex and after negotiating the maze that is their company phone system, I spoke to someone who seemed to know all about the problem. She said they were reformulating the product to avoid this going forwards. According to them, the sensor is not damaged by the orange Rainx but rather the sensor is "blocked" by the orange deposit.
No need for new washer fluid sensor I put the orange rain-x in my wife's 2013 JSW and the stupid light came on. I drained the fluid and put in blue fluid for probably 5 months and the light remained on. You can take off the front splash pan (8 torx screws), reach up, yank the sensor, and clean the exposed contacts with a scotch-brite pad.
I've been using the Rain-X washer fluid with de-icer in it for two winters and I haven't had this problem. I love this stuff as the temps here can get down to -30 C at times. This stuff combined with the heated washer nozzles will clear the ice off my windshield lickety split.
A few weeks ago I was running out of washer fluid and decided to refill with rainx de-icer since it was on sale, it's been very cold and I wasn't planning on bringing my car in for service for a while. Last week the wash fluid light came on again.
I've been using Rain-X Pink/Orange fluid almost exclusivley since the factory fill ran dry. We've been below 20F this entire week and not a problem with the fluid freezing.
