MB dealership can’t handle MBUX?
I’m in North Texas and took my new to me 2023 EQS 580 in for MBUX glitches and freezes as well as service B being due. I explained that service B was needed but my primary concern is that my MBUX was so out of date at 330 when current is at 505. As a result my MBUX freezes and glitches, and MB app shows I need an update that the car can’t see (it does have WiFi at home).
Their focus was that I needed new tires, brake pads (5mm left on an EV), and an alignment (which was just done). They were “finished” ($1k for service B, $2k for tires), but didn’t touch MBUX at all. Getting them to update MBUX was a real pain. Eventually they did do it and upgraded it to MBUX 505. Yay!
OH BUT WAIT… they also told me there weren’t able to find a way to update the maps (they said they were doing that gratis - so nice!):
I took the car back home at this point as the new tires weren’t in yet and they couldn’t figure out how to update maps. Confidence inspiring! The issue with MB app and the car disagreeing on the needed OTA update above persisted.
OH BUT NOW I AM ALSO SEEING THIS!
Can anyone tell me what I should tell these Mercedes wizards?
Better yet - can anyone tell me which North Texas Mercedes dealerships have better trained technicians? I won’t say which dealership this was, but I’m going to try to avoid a certain central-south DFW location for further work beyond tires or brakes.
Muchos gracias amigos! (please don’t write back in Spanish… I’m an idiot. )
Regarding the multiple error messages...
Many of us EQ drivers have had to deal with these from time to time. The short explanation for most cases is that too many individual on-board computers were sending too much information all at once to the central computer and this resulted in spurious error messages. Workaround was to lock and unlock the car three times in immediate succession and then walk (far) away from the car with the key fob for about 20 minutes. The real fix, was software updates - and most likely the one I have attached (read carefully on page 3). After the installation of this update, I never had spurious error messages again.
But unless it came with the paperwork when you bought your car, you will probably need to ask a dealer whether this recall update was ever installed in your car.

THANK YOU!
I gave that report to you attached to them this morning so hopefully that will make something happen. I took my car to a different dealership and I expect that they will do a better job. They seem to understand that it’s likely that the other dealership only updated MBUX and not IDC. The fact that they could immediately understand and explain that gives me a lot of hope this gets resolved.
Note the SECOND dealership is Mercedes of Grapevine, TX. I’ve heard some good things.
