Merged: Frosty wipers & unwanted wiping on startup

Does anyone else's window wipers do one or two strokes when you start the car, even when it's dry and sunny? This happens on about 80% of starts.

I've cleaned the sensor multiple times, but still happens.

The other aspect of the system I dislike is combining wash and wipe. Bring back the old system where I cold spray the windscreen without wiping. The current system scrapes the wiper across the sand and mud or ice on the screen before the de-icer washer fluid gets there.

On a previous car (VW golf), I could leave the wipers on auto knowing that there was some sort of sensor that stopped them from dragging across the screen on frosty mornings. So far I haven't tested this on the new car, just make sure that the wipers are turned off on a frosty morning before I start the car. Does the MB have this facility?

Yes, as Yogi says turn them off in the dry if you don't want them to inadvertently wipe, which was the same with my W176 as well. It hasn't rained on the A35 yet, so I've not turned them on.

Apparently, you're not meant to leave them on automatic.

They're automatic in regards to regulating the speed and frequency of wipes and not automatic in the same way that the headlights are - make sense?
