I have 99 C280 and I at least know why they went back to two wipers. The single wipe is aweful. In heavy downpours it just can't keep up. I have been thinking about searching online to see if they have ever been presented with it being a safety issue. THere were times when I thought I had better pull to the side of the road. If they had not changed it back to two I would not buy again.

 

Bloody hell, how heavy does it rain where u are? ive neva had that problem. Well done
I would suggest that if it was raining so hard that the single window wiper cant keep up u should slow down as the road would be very slippery

 

asside from the technical crap...girls like the wiper, so it stays

 

Well it was raining hard. But I was being passed by a lot of cars who either could see better than I could or were nuts! I liked it when I first saw it but it just has a hard time in driving rain.

 

The newer MB's have gone back to dual wiper blades due to the increased curvature of the windscreens on the new models. The old single wiper blade actually cleared more of the windscreen surface but works well only on relatively flat windscreens.
