Technical Bulletin (Sunroof / Sunshade, Will Not Open):
The sunroof's "Basic Setting" has been unintentionally initiated by the customer.
When the sunroof is closed and the rotary switch is pressed down in the closed direction for longer than 10 seconds, the basic setting program of the sunroof motor is initiated, and previous sunroof travel limits are lost.
If the basic setting is not fully restored (by continuing to hold the rotary switch in the down position until the sunroof has completed its full open/closed travel), fault codes (panoramic sunroof only) will set and the sunroof can no longer be opened.
This document discusses the "Fault Codes" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.
