Broken trunk potentiometer arm
I need some help fixing the automatic trunk closing mechanism on my 2008 E550. The plastic arm connected to the motor is broken, and I'm looking for the diagram so I can 3D print a replacement. I'd rather not buy the whole thing and want to use better material.
this is the part number for the whole unit 2118201597
Thanks!
