Replacing rain sensor...windshield removal necessary?
So the dealer is telling me the windshield needs to come out to put in a new rain sensor since its bonded to the windshield.
Is this true or not?
Thanks.

Interesting question. I have seen a windshield fully removed once and the sensor was still intact to the interior assembly. I'm still not sure about the bonding though as I didn't witness how it was removed. I guess this can easily be verified by getting something suitable and gently attempt to slide it in between the sensor and the windshield. If it's bonded, you won't get through. Try a playing card or a credit card.

Yeah I know where it is, and I know it is glued to the glass. But there is no reason you shouldn't be able to remove the sensor, clean the glass, and install a new one, in the car in my opinion.
I guess I'll ask about it later.

Agreed. After going to the parking lot and looking at mine, it seems entirely possible that this can be done from the inside. I wonder what the WIS procedure is, if one exists, to replace the sensor.

well they aren't telling me that they need to replace the glass, but rather remove the glass to replace the sensor.
if anything I'll buy the sensor myself for $58 and get after it with a heat gun and some brake cleaner.

ok, they are going to give it a shot without removing the glass.
These guys have been nothing but 100% straight with me so far, so I trust them at this point.
we shall see if they deliver.

I am assuming your car is still under warranty.. I'd just get a new glass. It will be cleaner than having somone put some glue or something on an old windshield.
If your car is not under warranty, it's cheaper to have a rock hit it and get a new one paid by your Insurance Company. mine got cracked and that's what I did. I also found out by my installer that the 1100.00 they charged the Insurance company would have been about 650 had I called them myself. HE also told me that when you get your window installe at the Mercedes dealer, they are the contractor who comes to replace the window. ( go figure ). my dealer wanted 1350 to install my glass and didn't want to file an insurance claim. ( joke ).
Anyway a brand new winsheild comes with the light sensors built into it. ad Honestly my new window works better than the original. He even swapped the benz sticker in the lower r/h corner.
