Mercedes windshield glass replacement

I just got a crack in my 2017 GLC 300 windshield. I am having it replaced with Mercedes part 2536709100 (Mercedes Windshield w/out tv tuner and w/o lane assist) at a local repair shop, not at a Mercedes dealership. I got the part number from the dealership from which I am leasing the car.

Is it safe to have the Mercedes glass installed by a non-dealer repair shop? I am not sure if the shop will need to connect or reconfigure any sensors when installing the glass and that is why I am concerned.

Thanks

Just had my front windshield replaced by a non MB shop that specializes in auto glass replacement. I have a 2019 GLC300 with auto rain sensor and camera located on the windshield. After the first rainfall the auto rain sensor was not working properly. After a long search online I found out there is a simple reset procedure that fixed the problem. The camera was calibrated correctly.

Is your replacement windshield regular glass or acoustic glass?

A point of clarification. The MB service manager informed me that the soft reset below is required because of glass density changes. I did not use a OEM windshield. Although the installer informed me that it’s the same glass....take that information for what it’s worth.

Soft Reset
with engine running and all passenger doors closed) start at [0] then turn on wipers to [III] position, then put the switch in the [0] position then put it in the auto [I] position. At this point have someone splash water on the windscreen (arm out the window) as the doors have to be closed to reset this function.

Regular. Non OEM. Third of the cost if MB replaced.

Good question and something I was very concerned with. While I was assured by the auto glass shop that they had trained technicians and personally witnessed the calibration, I decided to have my local MB dealer redo the calibration during a service visit.

Thanks for all of your very helpful comments.

Sigp232. It is regular glass, not acoustic glass.

I ordered OEM glass because I was concerned that when I turn the lease back in next year, Mercedes would require the returned car have OEM glass.

Plutoe, no it is not SafeLite, but the body shop is excellent (Also, it has cattle grazing behind it (really), not sheep, so I assume I should be OK.)

After reading the responses, I called the repair shop and was told that I would have to take my GLC300 to the Mercedes dealer to have the calibration done after it was installed, so I will take the car to the dealership to the get the windshield installed and calibrated all in one place. Thanks to all for the guidance.

I had a front windshield glass crack. It was covered by insurance. I got quote from dealer but their quote was way too high and the insurance company declined to pay in full.

I eventually went with safelite and was happy with the result. I used an OEM-equivalent glass. Everything went ok, Rain sensor worked properly. No reset on my side needed.

In retrospect, I should have tried requesting OEM part. Might be ok with insurance company since the vehicle was pretty new.

I've just replaced the windshield on my 2019 GLC 300 with OEM glass. Apparently Mercedes only had 1 option for my car to get OEM glass, the difference is the new glass doesn't say "Acoustic" but it is actually an acoustic glass. And also, there is no more a signature at the bottom right corner of the glass as it got replaced by "Mercedes".

The only issue that I have is that when I use the wipers, the passenger side's wiper comes to the driver's line of sight, as it used to stop at 90 degree angle. Not sure how to fix that?

Can’t get correct windshield

I’m having a new windshield installed and they can’t seem to get the correct glass.
The part number for my 2019, Glc 300 gives them a windshield with wires or an antenna of some sort on the sides. It also has a wire ribbon coming out the sides. My original windshield does not have that. Would anyone have a part number for the correct windshield? Mercedes only has one part number 253 670 0900 and that sends me the wrong windshield.
I have 2 cameras and a rain sensor behind the rear view mirror. Nothing else in my windshield.
