Question for 2019 G-Wagen Owner's - Cabin "Whistling"
The 2019 G-Wagen has water-tight door seals - and two small exterior vents at the back D-Pillar.
The customer issue we have diagnosed is at highway speed - with Climate Control on normal mode - those two rear vents produce a low volume but consistent "whistling noise" inside the cabin.
Question is - for other G-Wagen owners - do you have this "cabin whistling too" ?
Inquiring minds need to know to input upstream to MB Germany - let me know.
Keep the beat !

Germany's short term recommendation is (3) parts: (1) advise customer to turn Climate Control fan to 4 or lower - (2) remove rear door panels and remove two "foam channel blocks" each panel - (3) Front door inner seals - trim approx 3mm "gap" - items #2 and #3 deigned to let cabin air "breath" into door panels .
Germany has under long term research/advise future solution... no timeframe.

inwas, however, wondering what purpose the exterior vents on the back d pillar serve. When the car is running, there is a definite flow of air from the vents that seems to be powered by some fan

Thanks for the feedback - when Germany gets back to me on this lower priority "whistle" I will post back to the forum - keep the beat !




Its irritating. My dealer told me that they cuted a little a gasket inside of the right-side front ventilator but it did not helped much.
I see that latetst post is from april 2019 so quite long ago.
Does anyone have solved the problem?

Initially we thought it was from the door surround however the guys at MB taped up the door and it is still making the noise.




I noticed a different type of whistling, like a kettle boiling, after my door panel was removed to fix a damaged lock. The tech left a gap between the bottom of the window and the rubber/felt seal, and it now whistles. Mind you, this is on the inside of the car, and my whistling varies with the HVAC fan speed, for some reason. I think the bottom line is the window seals may be the culprit for you too - probably on the outside.



It turned out to be the driver’s side mirror was not fitting correctly.
Unbelievable!!!
I can 100% report that the noise has gone!
my driver side mirror continues to gently vibrate at speeds over 60mph and that’s after they replaced it once. Did your mirror frame slightly vibrate before and how’s it now? I continue to have this whistle noise issue
