W220 vehicles have heated windshield with rain and daylight sensors. Optionally windshield can have infrared reflective coating.
Facelift windshields have different rain and daylight sensor lens.
Aftermarket windshields for W220 are produced by XYG, Olimpia, Benson, FYG and Pilkington.
Pilkington is MB OE producer, therefore it is possible to order windshield directly from Pilkington much cheaper than from MB dealer. The glass will be identical to original MB glass, exept that windshield will be missing the small MB logo on the windshield marking.
For Pilkington glass markings VSG IR and VSG WD means the following:
V "Special Glass" and is a standard.
SG in German language is "sichereitsglass" (safe screen).
IR in German language is "Infra Rot" (termal screen or low transmition).
WD in German language is "wärmedämmend" (green glass).

W220 windshield is equipped with heating element in the windshield area of non-activated windshield wipers.
The heating element usually has cutout for the VIN number sticker, since
in US it is a federal requirement that the VIN number be visible through the windshield.
Vehicles with option code HEAT INSULATING+IR REFLECTG.SAFETY GLASS ALL-ROUND
are equipped with infrared reflecting glass including windshield, which reduces the amount of radiated heat entering the interior through the windows.
"IR" mark on the windshield denoting infrared reflecting glass.
Infrared transparent areas
The infrared reflecting glass also prevents the transmission of signals through the glass by in-vehicle electronic devices (e.g. electronic toll collection devices).
To allow the use of these devices in the vehicle, two infrared transparent areas (1) and (2) are placed in the windshield.
(1) Mounting location for electronic toll collection devices (infrared transparent)
(2) Infrared transparent area (pass-through for electronic signals)
(3) 31.5 in (80 cm)
(4) 19.0 in (48 cm)
(5) 1.75 in (4.5 cm)
Rain Sensor
In facelift vehicles there is no separate daylight sensor, since daylight sensor is integrated in the rain sensor.

Remove/Install
Disconnect ground cable of battery
Remove inside rearview mirror unit (A67) with cover
Detach electrical connector (1) at rain sensor (B38)
Release retaining clamps (2) on rain sensor (B38) to left and right
Remove rain sensor (B38). The lens (3) of the rain sensor (B38) is bonded to the windshield and must not be removed, otherwise the lens (3) will be damaged.
Install in the reverse order.
Perform function check
Read coding of the windshield adaptation for rain sensor and of adaptation of the light sensor booster factor using STAR DIAGNOSIS and replace if necessary, select windshield variant.
Connect STAR DIAGNOSIS, read out fault memory
Daylight Sensor
In facelift vehicles there is no separate daylight sensor, since daylight sensor is integrated in rain sensor.
For pre-facelift vehicles daylight sensor has part no. A2208203326.
Remove automatic light switch daylight sensor (B32/1). Lens of automatic light switch daylight sensor (B32/1) is bonded to the windshield. Do not replace.
Replace rubber spacers. Do not remove protective foil.
Prepare windshield (1) for glazing.
Align windshield (1) in the body opening. Observe gap - distance between top edge of window and front edge of roof. Dimension "A" mm 12.
Remove protective foil from rubber spacers.
Smooth sealing channel with hand roller.
Apply adhesive material. Install windshield (1) within 10 minutes before adhesive force of adhesive material starts to decrease. Height of glue bead approx. 13 mm.
Install windshield (1). Open a side window in the vehicle to prevent the windshield (1) from being pressed outward by air pressure when the door is closed.
The waiting time (time before vehicle can be driven) is approx. 1 h calculated from the time the windshield (1) is installed.
Install ornamental frame on wind deflector.
Install paneling on outside of A-pillar.
Install water repellent over wiper system.
Install wiper arms.
Disconnect electric connector (2) for heated window.
Install rain sensor.
Clip in automatic light switch daylight sensor.
Clean windshield (1).
Code adaptation of rain sensor and light sensor amplification factor and select type of windshield. Engine hood and driver door must be closed. Connect STAR DIAGNOSIS and read out fault memory.
