Hi all, my first post here!
I’m living Europe, driving a 2018 C-class Cabriolet.
My big project is to update (replace) the UMTS communication module to a LTE module now when the 2/3G net is closing down. I have acquired a LTE modem/module which is supposed to fit my vehicle, but I can’t find the UMTS one. I know that they are fitted under passenger seat in sedan/coupes but where in the whole world are they located in Cabriolets..? 🤔 Does anybody here know?

(I’m aware of that the new unit has to be SCN programmed in and registered with Mercedes via Star/Xentry.)

dreaming is always good
even if you succeed to do what we have done and get it connected to the network you will face a concrete MB wall

Thank you for your input!
Do you know where the Communication modem/modul is located on a A205 2018 Convertible?

Great! A million thanks! 😘I found the Burmester amplifier thingy (with a “computer fan” on it) just in front of the right taillight but then I gave up. Obviously I did not search far enough on the right side. 😄

Thank you! Unfortunately I hit the MB wall today. Seems you were right.
I’m at an authorized MB dealer now, they can change the vehicle code from 360 to 362 but they are not getting the module to connect to the MB system. They get an error message back.
They have succeeded in doing this job before, my car seems to be the first one to be denied. I assume the Germans, since a few day, have blocked this opportunity now.
Could also be that my used module is not working properly, of course, but I doubt.
Previously converted vehicles work still, I just checked. Unlucky me! 🤨

you see, told you

we got it all working even called MB with it
we added all possible SA codes to the MB servers
but you will get no activation from them with your vin

I guess that’s what’s happened to me/the dealer today.. MB won’t let anyone bypass their systems.

Peter is trying to say that it can be done if you ask him.

Andiee

Okay, but here at my dealer they say they get an error code.

Maybe Peter has a way, ask him anyways, it doesn't hurt to ask, worse case is he said he can't do it, can't hurt to ask : )

Well


I haven't been further with it, lack of time. it's not willing related it is MB database related

meaning that the activation button is not enable to the MB operator as long as the car VIN doesn't match

Hmmm, interesting, hopefully you can figure it out when you have time.
