I have a 1993 400e, how can I tell if I need the motor with the dust filter or not? Do I have to tear it down to tell, I would like to order the part before I take the car apart so I don't have the car down for a week waiting on the motor.
Thanks

Look at the windscreen seal under the wiper arm assem.. if it is a U shape , it has the filters..[ two]

Just did that job last weekend,,,, not bad at all. Ours did not have the filters and the parts man at Mercedes said not too many of them did have it.

Still don't know what I am looking at.
There is a screen that is right below the wiper motor? It pulls out it this the peice you are talking about?

I replaced the fan control modual last winter on my 400E. My fan worked fine.
The plastic screan is not the dust filter. My car did not have the filters.
I think you can the info from the VIN number.

Just pulled it apart no dust filter. I should have the new one on tue.
Thanks

There is a "smile" or "U" shape under the wiper assembly in the center of the car. If the U shape is hard plastic and held down with 5 or so phillips screws, there is no filter. If it is solid rubber, no fasteners, it has the filter.
