Vehicle Information
Condition
Sunroof / Sunshade, Will Not Open
The panoramic sunroof or sunshade cannot be opened. The following fault codes will set in fault memory of control module 4F Panorama roof (Vehicle Electrical System 2):
The sunroofs "Basic Setting" has been unintentionally initiated by the customer. When the sunroof is closed and the rotary switch is pulled down in the closed direction (Figure 1, "E" for longer than 10 seconds, the basic setting of the sunroof motor is initiated. If the basic setting is not fully completed, fault codes will set and the sunroof can no longer be opened.
This can also happen if the manual closing function is activated as a result of pressing button 1 for too long (Figure 2) when operating the sunshade. With the prolonged depression of the switch using a second finger, the rotary switch may rotate resulting in unintentional activation of the sunroof opening function (Figure 1, "E").
