Well I did as well for a time with no bad effects, by, when a VW tech, in a forum posting, advised against doing it on petrol engine cars for fear of trashing the fuel evap system, I took his word on face value - its the kind of thing smartish people do as this was no urban myth, but the words of someone in the trade.

yeah it does an initial wipe but afetr that it only moves when it sences rain, and the swith on top of the stalk adjusts the sensitivity i believe, correct me if im wrong...
You're wrong
Well for me anyway, I had a pretty boring drive up to newcastle and was wondering the second delays in between the different adjustments, ones 5 seconds, ones 10, ones 15 seconds.
Nothing to do with the rain on mine anyway.
Anyone know how to bump this to the top of the thread or is that admin wizadry?
Just copy it all and then go to edit your first post and paste it in

No, it is you that is wrong!
What you are describing is how the standard intermittent wipe works, what the previous poster was quoting was what function that switch performed on the cars with rain sensing wipers and auto dipping rear view mirror.
Well i'm right, he is right haha.
Nothing was mentioned in the original post about it being primarily for the cars with rain sensing wipers
just a general sweeping statement.Well i'm right, he is right haha.

Try again, the clue was in the OP's posting #5! Merry Christmas!
I was getting the impression that some people lucky enough to end up with an Ibiza with rain sensing/rear view mirror dipping, thought that all Ibizas had these features, if only! It was one thing that I specified when buying my wife's Polo back in late 2002 and I still think that it is very handy. Luckily Audi seem to fit that to S4 so as with my good old Passat V6 4Motion which I parted company with, my early 2011 S4 which I bought back in July, I still have these features, rain sensing gets annoying some times, but mainly it is brilliant.
Rain sensors have to be placed directly onto the windscreen in a little shroud otherwise they don't work properly.
One thought, have you got automatic air con or manual, if automatic? I'd think that that sensor is to monitor sunlight and so reduce heating when sun is shining. My daughter's Ibiza has manual air con and does not seem to have that sensor, my Passat certainly had one, think the Polo has as well and both of them have automatic air con, I have not noticed a sensor on the S4 though.

For anyone wondering if they have rain sensing wipers and dipping rear mirror, that picture clearly shows what the mirror assembly looks like if these systems are fitted to your car, firstly, the large round blob where the mirror fixes to the windscreen and the plastic cable way up to the roof.
