SUBJECT
Water Leak from Panoramic Sunroof
MODEL
E53 (X5 SAV), E61 (5 Series Sport Wagon) and E83 (X3 SAV) equipped with Panoramic Sunroof (S402A)
SITUATION
Customer may complain of a water leak from the overhead console area during heavy rain or when driving/parking on a steep slope facing downhill.
CAUSE
Possible Causes:
A. Obstructed or damaged drains or drain tubes.
B. Void in the windshield urethane bead.
C. Excessive gaps between the glass panels and the perimeter seal.
D. Inadequate water management system in the sunroof cassette.
CORRECTION
In case of a customer complaint, inspect various components of the sunroof system. Perform a leak test and then perform the recommended repair based on the outcome of these inspections.
An improved sunroof cassette with an optimized water management system has been implemented in production since 10/05.
The current improved part is available as a complete color keyed cassette as opposed to the bare frame previously available.
PROCEDURE
Inspect for the following causes and perform the applicable repair.
Cause A: (Obstructed drains)
Inspect the cassette drains and drain tubes for any obstructions or kinks in the tubes.
If any concerns are found with these items, they should be cleaned/repaired/replaced as necessary.
Cause B: (Windshield sealant)
Inspect the top edge of the windshield glass for any possible voids in the urethane bead.
Using water or compressed air may help in locating a leak.
If any voids are found, the windshield must be replaced.
Cause C: (Excessive panel gaps)
Inspect the condition of the perimeter seal and the gap clearance between:
1. The sunroof glass and the roof panel.
2. The two glass panels.
3. Note: 5.8 plusmn; 0.3mm gap all around (without seal) is required and can be measured with the special gap tool, P/N 00 9 341, or similar.
If any excessive gaps are found, adjust the glass panels as per RA 54 13 003.
If any damage to the perimeter seal is found, replace this seal as per RA 54 13 055 and adjust the glass panels as per RA 54 13 003.
Cause D: (Inadequate water management)
If no fault could be found with causes 1-3, perform the following actions:
1. If the vehicle was produced before 10/2005, replace the sunroof cassette per RA 54 13 080
If the vehicle was produced after 10/2005, do not replace the cassette but still perform the following countermeasures.
Note: The cassette available is the color-keyed updated cassette, complete with headliner and glass panels.

3. Replace the perimeter seal as per RA 54 13 055.
4. Install the absorbent pad kit as per the instructions provided in the appropriate Absorbent pad kit attachment.
