I have started a new thread as I had interesting experience when I brought my EQS in for service and this discussion does not dwell so much on software versions and what they do.

My complaints were: Adaptive cruise control would randomly drop out for 30 secs and then resume normally with no user warnings or errors. The traffic light assist function stopped working after the 316.x update to the infotainment system was installed. The fan in the overhead console buzzes when running.

What amazed me is the number of different modules in the MB architecture needed updating. For the cruise control problem, the tech updated the radar control software and the cruise control software. I am optimistic that the bugs will stop. For the light assist problem, he updated software for the camera system. He did not update to 329.x for the infotainment system. Previous threads indicated that would solve the problem. His actions did not solve the problem and I haven't seen any improvements to the camera system, but there are probably some bugs that have not shown up for me..

When I discussed the problems with the service advisor, I did not know how many subsystems were independent of each other; so, when I suggested that the car probably needed a software update, I was thinking of the 329.x update.

When the part comes in for the buzzing fan, I will be specific that the 329.x software will fix the light assist problem and probably remove other bugs in that software.

The point of this post is that Mercedes' design makes it very hard for the service technician to solve problems which leads to unhappy customers and unnecessary costs for MB. I think my MB dealer has one of the better service departments and it is not fair to them. Also, the customer doesn't get software updates before he has problems.

I think MB realizes what is going on as they are totally rewriting their software for 2026 which integrates all systems into one operating system and allows for over-the-air updates. Until then, I think, when we have problems, there will be a lot of trial and error to resolve an issue.

 

What I don’t understand is why some of us have had zero problems from the beginning and others so many problems. Why is the software almost perfect in some cases and so problematic in others?

 

I agree; we have 2 EQS's, both 580's, and one has had virtually no problems while the other has been back multiple times to the dealer.

 

it would be interesting to see build dates for each one. My guess would be early builds are the ones with the issues...

 

This has become one of the main issues with vehicle architectures. The Germans invented the CAN bus and modern luxury cars have 100-200 ECUs communicating over the CAN bus. What's worse is that all these ECUs are sourced from different suppliers. Each using their own software architecture and technology stack, so it's impossible to do a vehicle wide update. The various updates to fix issues have to come from the individual suppliers.

On the other hand, this distributed architecture has the advantage that if one ECU fails, the rest of the car keeps working. For comparison, my business partner picked up a Tesla Model 3 a few years ago. On the drive home his main computer crashed. The car kept driving as the driving functions are handled by a different ECU, but he had no speedometer, no control over the car functions, nothing. So each architecture has its advantages and disadvantages.

Tesla was the first car manufacturer that designed their cars with a common OS. Now the Germans are jumping on the same bandwagon. I just hope that future cars won't end up stranded on the side of the road if the main computer fails.

 

Both cars were manufactured in June 2022. When delivered, their software was out of date. I had the dealer upgrade from 2.6x to 3.16x on both cars. I do not think he updated any software except the infotainment software; so I assume both cars had the same software for all the subsystems. After that update, one car has had virtually no software hiccups while the other has numerous. It must be the luck of the draw. I have a close friend who bought a 450 6 months before we bought ours and she has not had any problems at all.

 

It's usually a combination of the specific hardware and subsystem software versions. Car manufacturers often have multiple suppliers for some of the parts or two cars built even around the same time are getting parts from different batches. Parts from one batch could be faulty or have newer or older software. The car manufacturers proudly say there are no two exact same cars rolling of their production line. With so many possible combinations of options, different parts suppliers, software not being on the exact same versions one product could be problematic, while another one is not. Happens in all systems. As a software developer and systems architect myself I can't tell you how many times I get feedback from a user that something isn't working on their machine and I have to track down what is different on their machine vs all the other machines where it runs fine.

 

My car keeps telling me that the charging door is open when it isn't. Otherwise, I haven't noticed any problems. EQS 580.

 

I have the same issue. It seems it might be something silly -- where the charger door 'arm' goes into the body, you can stick your finger in and push the small knob inward towards the back of the car -- can see immediately from the Mercedes me app that the car then thinks the door is closed.

For whatever reason, the plastic 'arm' doesn't seem to push the small knob enough to trigger the sensor from normal opening and closing.

For now I can wiggle it a bit to avoid the annoying warning popping up on the dashboard but not a permanent fix. Haven't had it pop up since the last time I closed it. Can't be bothered to go to the dealer for this yet....

 

This is a known problem; both of my EQS's had to go back to the dealer. At some point, you will be no longer able to open the charge door easily. The dealer adjusts the plastic arm slightly and the problem goes away. It is a quick fix and requires no parts.

 

I have a 2022 450+ with the original software (2.x) and I am almost afraid to request the dealer for an update as I have had no problems. I am not sure what new features I would be getting with the update and if it breaks anything, i feel the techies would be on a wild goose chase. Big believer of "if it ain't broke, don't fix it".

 

I had various problems with my EQS 580. Navigation stopped working on most occasions, head-up display stopped working and multiple other error messages. This week the dealer replaced the “control unit”. Most setting were set to default. They also updated everything to the newest SW version. I am now on E330.602
does anybody have any information on new features and bug fixes of this version.

thx!
