Modified Wedge System
The tailgate of the E70 is split in two in exactly the same way as the tailgate on the E53. However, the wedge system is different from that of the E53. This wedge system was copied from the E61 and must be adjusted correctly.
It is important to note that there must be a system or initial stress between the wedge and the limit position in order to guarantee the full effectiveness of the system.
This adjustment can be carried out from inside with the tailgate closed. However, it can also be carried out from outside with the tailgate open.
As the tailgate is relatively heavy, a combination of gas springs and barrel springs is used to ensure operating convenience (spindle system). The hinges for the lower hatch can be separated at the lower part of the hinge.
The lower tailgate is no longer unlocked electrically as on the E53, but mechanically via a release lever. The automatic soft-close on the tailgate above is not integrated into the lock as on the E53, but is designed as an automatic soft-close clamping bracket.
