Anyone else have this problem with rain-sensing wipers?
Whenever my wipers are set on automatic mode, about once every two days I get a few phantom wipes within the first 5 minutes of driving, on a bone dry windshield. Sun is shining, not a cloud in the sky, and there go the wipers.
It seems to be random. Perhaps a buildup of pollen on the windshield is triggering the sensor? Don't notice anything, but perhaps something is there.
This isn't a huge issue, but it really renders the auto-wiper feature unusable, since my understanding is that consistent dry wipes aren't good for the wipers or the windshield.
Anyone else have this problem, and if so, is there a fix from MB or a home fix?
Other than this problem the rain-sensing wipers work great, and I love this feature -- shame to let it go to waste.

same here, i never have it on unless it starts raining. i did leave it on once to see if i could, and it did the same thing - randomly wiped the windshield, so i turned it off.

same thing happens on our w220...within the first few minutes of driving with it in auto mode, it'll swipe once or twice.
I asked the dealer once while we were in for service...apparently they can reflash the rain-sensing software or something like that? They say it may be the software gone nuts :p

It is actually not supposed to be left in Auto mode with the windshield drip. When it wipes a dry windshield you are just asking for trouble as you drag the dirt and debris across a dry windshield you will scratch the glass. And yes mine wipes if accidentally left on oncde at startup.

i never turn on the rain sensing wipers unless it starts raining. then turn them off. this is what is instructed in the owners manual, also dont leave the rain sensors on when you take your car to the car wash.

Keep it turn-off if not raining to save your windshield.

my friends GTI is that way you never have to turn them off as they wont wipe when you turn on the car if it isnt raining. mine will wipe once when i turn on the car if the auto rain sensing wipers are left on, whether its raining or not. it doesnt bother me that i have to turn on the wipers when it rains, i dont have to adjust them or anything. besides doesnt rain the much in so cal anyways.

If you leave it off until it rains what's the point of getting it anyway ![Smilie](https://mbworld.org/forums/images/smilies/smile.gif)
What I found to be causing this phantom swipe is actually tree or post shadows tricking the sensor... Near my place there is a huge tree and whenever I go by it wipes, this happens only around 11:00 - 14:00 when the sun is way up there....
According to my SA the startup swipe is normal when you leave it on auto.
cheers

the first month i had my car we were having really bad rain storms in san diego. the hardest i have ever seen it rain. i was going like 30 mph on the freeway, anyways i had to put it on max manually. other than that the wipers seem to work fine. maybe an extra wipe here and there but never have to worry about them going fast enough except that one weird week of rain.
