Plug in my Mercedes

[CoralNova]

Hello everyone. Has anyone ever used the OBD plug for a Mercedes-Benz? Yes, I understand. A lot of my applications aren't working, according to 2017 cla200 and Merc, since the 3g network is closing. However, I've noticed that there are a lot of OBD devices that you can connect in to make them work again; however, I'm wondering if these devices still use 3g. If they are, then I'm essentially throwing away my money. Since Mercedes stated they stopped making these a long time ago, I'm simply trying to find out more information on them.
I want to thank everyone.

Indeed, they were removed from the market a number of years ago, and alas, the software has been deactivated, so neither your existing nor newly purchased device will function.

Although most aftermarket OBD2 readers focus on reading diagnostic codes, there are a few that may do comparable functions.

The 3G network has already closed, in my opinion; it is not "going" to close. Neither my location nor what appears to be yours has any 3G coverage.

One of our C-class features a 3G communications module. Thus, the 3G connection is inoperable; nevertheless, 2G is still utilised for real-time traffic. Years ago, the internet connection was supposedly "switched off," but that's a different tale.

My wife may still monitor the status of our vehicle using the Mercedes Me app on her phone. This suggests that it can "speak" to the vehicle. Presumably, this is occurring over 2G. Seeing the vehicle's position and having the ability to lock it remotely are not supplementary features that we pay for.


To far, my sole experience with diagnostic tools has been with OBD-II plug-in devices.

Adaptor for OBDII Bluetooth Mercedes-Benz is dead.

It is possible to upgrade the car's modem from 3G to 4G, and the Mercedes me App operates over GSM. As of 2018, the 4G modem was standard for MB automobiles.


While this will get the Mercedes me app working again, you should know that it depends on subscriptions, which aren't cheap.

Being an American writer, I will preface this by saying that I am sorry if my spelling and punctuation are incorrect.

The 2017 e300 and the 2021 e450 All-Terrain are the two MBs that we own. The e300's navigation system isn't updated or functioning correctly anymore. As of December 31, 2025, we are aware that the 3G module will no longer function and that the mbrace service will be discontinued. Unfortunately, Mercedes-Benz is out of options when it comes to fixing this problem.


We had the navigation map upgraded to the most recent version at our MB Dealer for our e300, however it is still acting problems. Furthermore, we are unable to pair our mobile devices with the vehicle's Bluetooth system. Neither of our cell phones will pair or be recognised by it.

It appears that there are no solutions while looking for a remedy.

How is this problem being addressed in the UK? It seems to me that 4G has been available since 2009. Why Mercedes-Benz waited till 2019 to implement 4G is a mystery to me.

Would you have any thoughts to share? Who needs this hassle?

Will my phone's built-in Wi-Fi allow me to access the Internet when I put it into a power outlet? "I know a lot about a lot of things, but I'm a master of nothing."

That's fascinating.🤩
