How to open the trunk mechanically
Hi guys, my name is Peter, I'm new here and have a major problem, please help me 
I have 2022 R232 with battery issue, there is no power in the car and can't open the trunk to change the battery.
I opened the car with emergency key and tried to open the trunk by the positive "+" under the hood, but nothing happened, there is still no power in the car. Like the car is in some deep sleep mode, there is no power anywhere in the car.
So, how can I open the trunk mechanically? I read the user manual but the only chapter for my problem is about unlocking and opening the trunk from inside with the emergency release, but how to get to the button from inside the trunk?
The dealer said, bring the car to us, but it's 300 km from them in my underground garage, no way to take it out.
Regards,
Peter

No more MB:(
These battery issues have got be one of Mercedes greatest failures. Only a contortionist knows how to operate these things. Sorry for the rant OP, I'm sure someone with first hand experience will chime in. Good luck.

Why don't you open the hood and attach a battery charger to the terminals in the main engine department and charge up your battery?

When the battery voltage is under 11V the charger don't run, in my case the voltage is 0V, I got none power in the car. I attached the battery jump starter on the terminals in the main engine department just to open the trunk, but doesn't work because the battery is obviously complete dead. The guy from the battery shop told me that I perhaps got a dead battery cell and the only option is to mechanically open the trunk and replace the battery.

Why don't you make this the dealer's problem rather than yours. I am not sure where you are located but let them come to your house to get the job done or worse case send a flatbed back to the dealership?

Honestly, I didn't expect it to be such a problem, I thought I would just open the trunk and change the battery, I didn't expect that there is no option for mechanically opening the trunk.

it's complicated, the car is from USA and my dealer here in Europe still waiting for permission to cover the warranty. Eventually it will happen, the dealer will collect the car but I don't know when....and how because the car is in the underground garage in my mountain house where can't enter pick up truck.

Now I get it, you are in Bulgaria with a US Vehicle - that really does make things interesting and I hope your local dealer will handle this differently than what would happen in the US with a " grey import".
I had a similar situation with a totally dead battery on my Ferrari. However, we were able to get the car going with a proper jump start device and once the car was running it allowed us to operate all the facilities.
You may want to get the local roadside service to come with their big truck or charger and give this a try,.
Good luck!
PS - I have called my local guy to find out if there is a mechanical way into the trunk - if there is a way I will let you know.

Here is what he says, which mirrors my thoughts - good luck.
"I do not know of a manual way to open the trunk BUT there should be the jumping points under the hood. Once a jumper box is connected to the car the trunk should be able to be opened. Just a thought."
Lastly, I would strongly recommend that you have a trickle charger permanently installed in your trunk - it is a piece of cake for any repair shop to do that. This will avoid this issue in the future.

I had a similar experience on a different car - I had the "NOCO Boost HD GB70 2000A UltraSafe Car Battery Jump Starter" - that thing has a special button to force charging even if the battery is at 0V. That did the trick for me.
Hope that helps.
