Rain sensing wipers are annoying!!!
That only aplies to pre-'05 W203's. In '05 W203's the rain sensor and light sensor are built into one unit with a single plug.

It is really annoying for me.
During slight rain, just a teeny bit of acceleration can cause the wipers to swing like mad.
Another problem is because my wipers squeak very loudly. If my wipers aren't noisy, probably I won't be annoyed.
I don't have RainX, I am not sure if the squeaking is caused by the Mequiar's car shampoo (I don't use that shampoo on the windscreen but they may have overflowed over it during washing).
My 02 C240's auto-sensing was working fine, almost too fine.
I replaced the windshield with another OEM one due to a crack, and the new windshield came with a sensor. Of course in sunny CA it just started to rain a few weeks ago, and I am noticing the same thing: in a slight drizzle while the other one would have functioned perfectly, this one just keeps going and going, no different than the ON (low) mode. It sometimes works fine, but mostly works constantly.
I was hoping that I would find out here how to change the sensitivity (like turning a screw or something on the unit), but I guess I am stock with a bad sensor.
Any ideas from anyone??
