SITUATION
A wind noise or water leak may be present due to an insufficient seal between the sunroof glass panels and the perimeter seal. This insufficient seal typically takes a year or longer to cause any noticeable problems.
CAUSE
^ The hollow/bulb-style seal has taken a permanent set in the compressed position.
^ The seal material has started to deteriorate over time.
CORRECTION
Replace the seal using an updated part, which utilizes a different material with improved durability. In addition, the geometry of the seal has been optimized for improved sealing.
In conjunction with this new style seal, some vehicles may requite a coding update to avoid future problems pertaining to the anti-trap protection being activated when no obstruction is present.
PROCEDURE
1. Replace the perimeter seal per Repair Instruction REP 54 13 055.
2. E60 and E61 vehicles produced up to 11/2008:
Program the vehicle using ISTA/P 2.31.2 or later
E70 and E71 vehicles produced up to 3/2009:
Program the vehicle using ISTA/P 2.33.0 or later
E83 vehicles produced up to 6/2009:
Program the vehicle using ISTA/P 2.34.0 or later
E91 vehicles produced up to 3/2009:
Program the vehicle using ISTA/P 2.33.0 or later.
E53, E65, and E66 - No updates are required when fitting the updated seal to these vehicles.
Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the latest software.
For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal / Service / Workshop Technology / Vehicle Programming.
Other models covered by this Service Information do not require a coding update.
3. Initialize the sunroof per Repair Instruction RA 54 0... and then operate it several times to ensure that it does not activate anti-trap protection. If anti-trap protection is activated, ensure that the perimeter seal is properly installed and readjust the glass panels. This situation is quite rare.
