Subframe
Removing
• Removing and installing the right subframe is described here. Removing and installing the left subframe is identical.
• The removal and installation of the subframe is different on the sedan and wagon.
The window regulator, door lock and speaker are secured to the subframe.
The door lock can only be removed with the subframe.
The subframe can be removed only if the door window is detached at the clamping screws on the window regulator.
If it is not possible to drive down the door window by the electrical window regulator, first the exact cause of malfunction must be determined.
Check the comfort system DTC memory with the Vehicle Diagnostic, Testing and Information System (VAS 5052 A) for the Comfort System DTC memory.
If electrical malfunction is present, repair this malfunction first.
If there is an electrical fault via the window regulator motor, this can be unscrewed from subframe. And the door window can be slid by hand into the necessary work position.
