Car is DEAD. '02 CL500
Wife accidentally left the key in the car overnight. There is no power in the car. No dome lamps, no soft close etc.. Cannot open trunk or even turn the key! I am attempting charging the car with a battery tender hooked up to fuse F9 (air suspension). Can anyone tell me a work around on this?
Any help is, as usual, greatly appreciated. Will |

How do you get to the battery if you cannot open the trunk ?? I believe there is a plate underneath the passenger side floor which lets you hook up to a cable to charge the battery ??
Here is a video where to apply power . https://youtu.be/Jb_7E-Z5D7g Just apply power under passenger carpet to pop the trunk . Dont jump start from there then once trunk is open charge the battery by connecting directly to the battery |
Trunk opens with the metal key to access the battery

Thanks for the help. I finally got the emergency key to work in the trunk, so I could access the battery. I tried charging at the point under the passenger foot well, but the battery was so dead it would not charge! There is a video on YouTube by Mercedessource on how to restore AGM batteries. Easy trick. My batt showed 0 volts on my multimeter. After using this method the battery came all the way back and is holding at 13.2 volts! I had to reset all the windows and sunroof and I had a couple of error messages, but they went away after driving for a few minutes. Just gotta love the internet. Please check out Mercedessource. You guys probably already know about this.

Hi guys,
I have the same problem. Opened up the passenger side foot panel and i see only one point. Not sure if i should connect positive on this. Or should i dig deeper and take the rubber bit off? Also it doesn't help that i can't open passenger door as the car is parked next to a wall!. :wall: Please help.
