yes looks like the nut has come loose... have you been using your wipers on an icy screen in the morning

Nice GIF, what software did you use to convert video into it?

With these wraparound wipers, do MB use 2 motors, or is there a bell crank to offset one wiper from the other?
There's a subtlety in the design of these wipers which may not be imediately obvious, but, if the two wipers ran at the same speeds, they would cross and clash, so, one wipers needs to lag the other while they're close, and then speed up later in the cycle.
This speed variation can be done the expensive, but dull, way, by having 2 motors under computer control, or, the clever way by interposing a bell crank in the linkage to one wiper.

There is a complex passenger arm arrangement to create the correct sweep.
I suspect either the drive linkage has come apart or the active cam nut/spinidle has come apart.

I showed that image to a friend of mine (who's into Alfas) - his response:

If the linkage is mirrored for LHD cars, then, yes, I would agree, but, if the linkage serves for both types, then, no, it is solving a real problem.
Of course, the best solution is to have one wiper, mounted in the lower edge middle of the screen, and a clever linkage to make the wiper sweep further into the corners.

This is Mercedes not BMW, they don't bodge LH wipers onto RHD cars.

You mean like the panoramic wipers fitted to W201 and W124 models ?

Yes! It's one of my favourite featues on our W124.
At the cost of some complexity with the linkage, one type fits both LHD and RHD cars, and works equally well on either. So, the extra cost of the linkage compared with two parallel wipers is partially offset by the reduction in version and configuration control.

Be glad their research of the early seventies didn't go wrong- they'd looked into ultrasonic rain repelling, vibrating glass, air jets, all manner of ....uh.... "inventive" solutions to getting water off the screen.... and determined wipers work best. Another bullet dodged.
