SI B54 02 05Special Roofs
July 2005
Technical Service
This Service Information bulletin supersedes Service Measure B54 201 05 dated April 2005.
SUBJECT
Panoramic Sunroof Will Not Close From Vent Position
MODEL
E53 (X5) produced from 9/2003 until 11/2004
E83 (X3) produced from 9/2003 until 11/2004
SITUATION
When attempting to close the panoramic sunroof from the vent position, the anti-trap function is activated and the sunroof will not close. This problem can occur after the vehicle has been exposed to direct sunlight for a long period of time.
CAUSE
Gap tolerances between the seal and the sunroof glass are reduced due to heat expansion.
This can cause the anti-trap function to activate.
CORRECTION
On a customer complaint basis, recode the panoramic sunroof control module (SHD).
PROCEDURE
Recode the SHD using CD 39.0 or higher for E53 (X5 SAV) and CIP 16.0 for or higher for E83 (X3 SAV). Coding the SHD will increase the anti-trap threshold to compensate for thermal expansion.
E53 (X5 SAV):
^ Select Coding/Programming
^ Select ZCS/FA Coding
^ Select E53 Series
^ Select Recoding
^ Select Panoramic Sunroof
^ Complete the coding procedure by following the on screen prompts.
E83 (X3 SAV):
