hello all,
another update from me returned from dealer with car, what they told me diagnostic machine popup an update and they have installed , when I return home I notice mbux and the mobile app was in same status, i forget to check sw version of mbux. Only idea i got now at the moment some software confusion going on at background or some another software version already installed it as whole package i.e. e445 or e505 and prevents that one, similar that you can not install apps from android because made for prev. versions, as @JO2025 mentioned maybe not worth to go to dealer and give it a time I needed balancing so it was ok for me to visit.
Today I notice pending update dissappeared from mbux and on mb me app its not as notification anymore but still exist in OTA section of app, I can see its status as "not required"

My EQS has been stuck on this update for months. I even took it to the dealership, where they updated the MBUX OS, but this update remains stuck.
Its annoying because I keep getting the popup when I start the car that there is an update to apply.
I'm going to plug my mother's car into a 12V battery charger for a say to see if it'll be happy enough to apply. MBUX says that the battery charge level is not adequate. Of course, this refers to the 12V and not the HV battery.
If the 12v battery isn't fully charged (for whatever reason), an OTA will not complete. I've been down this path before-- ended up getting my 12v battery replaced because it was determined to be defective, and boom. the OTA's ran without a problem. If MBUX or the App is telling you that you're not fully charged, see your dealer.

Is the app also saying the state of health of the 12V battery bad? There are two menus, one is state of charge, the other is state of health.
Thats what mine said-- the state of health was Poor for Battery Health. And as long as that was there, no OTA updates would complete. Once I had the 12v tested and then replaced, it completed all pending OTA's at the next On/Off cycle. Even if State of Charge on the 12v was fully charged, it wouldn't run any OTA's.
So there's apparently some check in MBUX before it'll allow OTA's to run -- and one of those conditions is the State Of Health on the 12v.

I see, that should justify a warranty replacement by the dealership, they can't deny a warranty replacement under the wear and tear period.
Correct- it was determined to a failure of the battery itself, so it was replaced under warranty (this is in the US, so things might be different) without an issue.

So around 2 week ago i got my first OTA after i pick the car : "Software update for vehicle charging system: Occupant restraint controller", i think download was fine but it stuck on installation, i tried to turn off engine, park mode&brake, it was still there , info popup gives a tip about battery level tried on 60%, 70% ... 100%. Non satisfied installation conditions, anyone familar with this one? I am adding screenshots and mb version, my 12V status shows charged but health is still "calculation not yet possible" i dont know if its problem, service said if i can not solve it stop by next week, MBUX : RL_NTG7_E445.001_23364AC3
Updates
I have the same issues, in fact, about 4 updates waiting. The dealer could not get it working either, so I said they can try again when the vehicle goes in for a service.

It's the 12V battery. As soon as dealer replaces it, the update will proceed. That is the "technical" constraint. Have them test the 12V (don't rely on the app, it's wrong as far as the car's sensitivity for an update goes), it will show that it is faulty. After replacement, the update will work immediately.
yes 12v biggest suspect, myn still same as last post in status not required on mobile but nothing in the car, i dont know if it matters or related but dealer run some fw update on seatbelt controller when i was at a2 service, i also read there was some bluetooth vulnerability fix mb working on prob. we will get update for that next.

I had my EQE SUV in for service yesterday for the OTA application failure. The 12V battery tested OK The tech applied new charging software, which was supposed to address the issue, but it didn't. Tomorrow I'll return the car for them to replace the 12V battery, even though it shows good on the test sequence. I've already talked with the Service Manager who has agreed that the only thing left to try is the battery replacement. I'll post the results back.
If it's not the battery then the car needs to be updated in the workshop. Couldn't install the update for weeks. The workshop took 4 days to fix the problem with the help of the department responsible for OTA updates. Now I was finally able to install the update.
Some people may also be contacted because a customer service measure regarding the OTA update problem is to take place. I was told this a few weeks ago. But my car was not among the affected vehicles. Some customers from Germany and the USA have already been contacted.

The dealer must open a technical case due to the inability to update the software via OTA. The service shop has updated all of the software that appeared to be related (and indicated), but the OTA updates still show that a "Technical Condition" still needs to be satisfied. The battery checks out OK, and the voltage levels are correct. I'll keep posting of the results.
Over the Air.
Everyone might not know what an OTA update is.
It’s essentially, as I understand it, a cell phone signal that is sent and received passively, with software coding, to update onboard software based systems.
My understanding is, it waits until the car is in a shutdown cycle, or recharge cycle to onboard the update.
A lot of the newer MB models have a similar update system.

OK, the following is the result of the PTC:
"The OTA updates will not clear for another 4 weeks due to a change needed in the back-end servers." My tech updated all of the relevant controllers in the shop, but there is no workaround for the OTA message which is really that my vehicle already has the required updates installed, but the system cannot deal with the fact that the OTA software cannot be applied! The problem is NOT the 12V battery per a previous suggestion.

I needed balancing so it was ok for me to visit.
