SL55/63/65/R230 AMG: Trunk stuck
I hope one of you can help, l removed the ancillary battery to replace it, shut the trunk and now it won’t open with the small metal key. Is there any way of livening up ancillary circuit from the font of the car so I can try opening using the key fob.
this normally wouldn’t be a problem but to open the fuel filler cap you need the ancillary battery plugged in which is one I’ve removed from trunk that won’t open.
ive been searching through all the threads and may have found a way in via the trunk brake light. Being a sl55 amg you cant get to the trunk from inside the car so this maybe my only way in.


I had similar issues along with other symptoms. Having to replace at least the motor and impeller vanes in the PSE pump box.
