Does anybody else hate their rain sensing wipers?

how do you all know it's the same sensor? AFAIK the rain sensor is part of the windshield mount on the windshield (the dark circle,etc.). I know this because when I was thinking of replacing my windshield, the glass guy told me to make sure I specifically ask for the windshield with rain sensor (i.e. there's a windshield with and one without). The sensor for the headlights is definitely not on the windshield and I find it hard to believe they use the same sensor. I think someone is just making this up. Last time I read, rain sensors use infared light to detect drops of water, etc. how the hell could this be used for headlights?!?

My rain sensing wipers work perfectly now. I changed my auto headlight setting from late to med and presto, the rain sensing wipers work to my liking. Thanks for the tip!

Had them on my b7 and now b8...They are the best! Keep it at the lowest setting and its highers and lowers the speen (on auto) depending on the rain. I've never had a problem on highway or city traffic. Occasionally i have to put it on full blast but thats at 75mph thruway speed with tractor trailor or suv in front of me

rain sensing wipers can be changed to regular intermittent
The rain sensing wipers on my '09 A4 have never worked well....today the dealer discovered that you can go into the computer and disable them without affecting the automatic lights. I'm now happy as can be with regular intermittent wipers with 4 settings!

Whoa! I want this! I wonder if the procedure is common knowledge among dealerships at this point?

I believe I successfully disabled the rain sensor with vagcom but this would have affected the light sensor too probably:
09-Electric
07-coding
long coding helper
byte 22 - rain/light sensor installed (checkbox)
I unchecked this and it seemed to make the wipers run in regular intermittent modes while at speed. The wipers did slow and stop at times when the car was stopped. I re-enabled the rain sensor awhile later to see if I'd get used to the sensor and find it useful. I'm still on the fence on it. Why not allow the intermittent settings to be intermittent and have a different setting on the stalk for the rain sensor? Easier to mass produce the same wiper stalk I guess. As for the light sensor, I don't use it at all. I run with parking lights during the day and manually turn the headlights on at night.
If one of you does not have the ross-tech cable and really wants me to test it out more between the wipers and lights, I can do it soon. I did not see a dedicated option for just the rain sensor with vagcom but I may have missed it or it is not obvious.
