Dealers obviously know of this issue but don't disclose? Didn't make noise on test drive, but did on day 2, so tells me dealer likely recalibrated before test drive knowing the issue. Current solution presented by our dealer is to put foam or rubber in walls of car to lessen noise. Ridiculous - CA lemon law attorney anxious to represent us but seems like a year long process.

So, what does the diagnostics say exactly? This thread is getting a bit old as we keep speculating about calibration, when diagnostics can likely tell you if it's calibration or not.

Ask the dealer to hook it up to diagnostics and drive with you. Multi-function camera and parktronic modules have two data point exposed something like: Initial calibration - Performed or Not, then who performed it - Factory or Service, then there is "Drive calibration" that shows current drive calibration status. They should be able to see if Initial or Drive calibration is not completed and camera open / close events correlate to diagnostics calibration status. If it's indeed related to one of these two calibrations, they can file a request and ask MB WHY calibration never finishes or doesn't persists after that, not just "the camera opens and closes". Additionally, dealership likely can perform initial calibration by themselves but they may need some extra equipment from MB for it.

From the work order:

126 C/S THE BACK UP CAMERA IS CONSTANTLY OPENING AND CLOSING. PERFORMED INITAIL ROAD TEST TO VERIFY CONCERN. PERFORMED SHORT TEST SHORT TEST FOUND NO RELATED CODES, PERFORMED ROAD TEST AT 9:55 AM TO MONITOR REAR CAMERA. NOTICED SDS SAYS CALIBRATED SUCCESSFUL, BUT CALIBRATION PERCENT IS AT 0. ROAD TESTED AND CAR IS RE CALIBRATING REAR CAMERA UNTIL IT REACHED 100%. THIS WILL STAY AT 100% AND WILL NOT RE CALIBRATE UNLESS CAR SITS FOR 120 MINUTES OR SO THEN STARTS CALIBRATION OVER AGAIN. PERFORMED ROAD TEST WITH SDS WITH STOCK UNIT RJ602007 AND THIS CAR PERFORMERS IN THE SAME MANNER. OPENING CASE TO SEE WHY CAR IS LOOSING CALIBRATION AFTER A SUCCESSFUL CALIBRATION HAS ALREADY BEEN COMPLETED. WILL UPDATE AFTER RESPONSE BACK FROM MERCEDES ENGINEERING. Case number245821940 This is a normal function. LI54.65-P-066284 does apply. Please also see March of 2021 PCTT as this has more information on this calibration process. The cameras are calibrated at every sleep cycle. This is not a malfunction, but an intended system behavior: Calibration of the reversing camera is in progress. For this, the cover on the camera is opened for max. 5 minutes in forward travel. The calibration can be performed as long as the vehicle speed is < 18 mph and the steering wheel angle is < 10~. If these criteria are no longer satisfied before calibration is complete, the calibration sequence is aborted and the camera is retracted. The sequence is restarted when the criteria are met again.

Ok, it seems like they actually were pretty thorough investigating it. The problem I see here is that their stock unit performed the same way so they had nothing to compare it against, which is unfortunate. The reason I believe it's important is that if you have two cars that perform differently, MB can no longer say "it's normal", they'll have to explain why the units are different.

That work order explains the difference.

I wasn't aware of any of these calibrations.

I actually don’t think the work order explains the difference. The tech actions align perfectly with my suggestions above, that’s why it looked to me like a rather thorough investigation. However, because their stock unit (as in another GLE they had on a lot) behaved the same way, they had to accept “it’s normal” answer from MB Engineering as they didn’t have a car without the issue to compare it to and call MB on it.

We have this on my wife’s new A200 and when we took it back for inspection they told us it was normal. Hard to believe that MB would produce cars knowing they make a noise like that. I have a GLE 450 on order and I’m considering cancelling the noise is far to loud

We are having this same problem here in the UK on the GLA and A Class saloon ( Sedan) It is driving us nuts also. I have returned my car to the dealership and they are fully aware of the problem but are unable to alter the software as it is set by M/B. I have also sent a number of Emails to their customer services, but they just come out with the same old twaddle !! that it is not a fault but a characteristic of the vehicle, well all I can say is that it is a damn stupid characteristic.

Mercedes Benz client of many years standing but will never buy another.

Shoot...I was going to order a GLE450, 2025 when available, but now will hold off until I see this issue is resolved by following this thread.

Hollington

"The camera is open for max 5mins in forward travel" That has certainly not been the case in my 2024 GLA, mine will still be clanking away after 45 minutes or so, and still M/B refuse to anything about it.
M/B client for many years, never again.

MB's mindless marketing nonsense is part of the problem. When I disable "paktronic" from the main screen button the camera keeps popping out. But when I do it when "parktronic" is actively looking for parking spots it stops popping out. So I guess I 'm talking about two different "parktronic" systems.

Anywhosies, I'm just glad the new G comes with EQ technology. That's much less confusing.

Have a brand new 2024 EQA250+ facelift. Can confirm it’s doing the same thing in this model too. Being a quiet EV the noise is really noticeable and annoying. Going to take it into the dealership soon to see what can be done but it sounds like it’s a common issue.
