topic titel says it all.. i dont now howe to remove the backseat ( not the lower part but the backrest part )
I am not sure that it is necessary to remove the rear seat back in order to gain access to the traction battery. If you open the hatch and take out the folding floor panel and the black plastic tray covering the spare tire, then you can see to what extent the hatch inside trim has to be removed to give you sufficient clearance.
the back rest for me is part of the back seat! i already removed it and you do not need to remove the back sitting only the back rest directly behind the HV battery side where you need to acces the HV cabling and battery ecu in the pdf you can see where you need to take 2 bolts out.
