SUBJECT
Water Leak from the Front of the Sunroof
MODEL
E70 (X5)
E71 (X6)
SITUATION
During extended periods of heavy rain, water may enter the vehicle from the area around the front of the sunroof cassette, the Roof Control Panel
(FZD), the map lights, or the A-pillars. The customer may also simply state that the carpet in the front of the vehicle is wet.

CAUSE
The sunroof cassette is overflowing due to the fact that one or both of the front sunroof drains are trapped or twisted.
CORRECTION
Gain access to both drains and untwist or free the drain tubes, as necessary.
[NEW] PROCEDURE
^ Blow compressed air into each of the front drains on the sunroof cassette to ensure that no debris is clogging the drain. If debris was present and
has been dislodged~ the following steps may not be necessary.
^ Remove both the left and right kick panels to access the point where the lower sunroof drain tube exits the lower A-pillar to access the drains:
a. Remove the left and right kick panels per Repair Instruction RA 51 43 075 (left) and RA 51 43 075 (right).
b. On the left side, remove the Footwell Module (FRM) from the A-pillar per Repair Instruction RA 51 31 115.
c. On the right side, remove the lower instrument panel cover.
d. Pull back the carpet behind both kick panels to expose the opening into the A-pillar, where the drain resides.
^ Inspect the drain tubes (inside). If they have been rotated around and are kinked, rotate the drain tubes back to a position where they are no
longer kinked. If the drain tubes are not kinked, proceed.
^ If the drain tube was not kinked in that area, remove the fender liner in order to inspect where the end of the drain tube exits the car.
a. Remove the fender liner on the side[s] that is kinked per Repair Instruction RA 51 71 038, in order to inspect the end of the drain tube, to
ensure that the spout is still facing downward.
b. If necessary, rotate the spout enough for it to face downward, ensuring that the tube on the inside of the A-pillar is not becoming kinked
again.
^ If the end of the tube is being pinched by a foam block on the back side of the fender, pull it free and trim off about 10 mm of material from the
end of the tube, so that flow is not restricted in the future.
Note:
If a drain tube (one or both) is found to be permanently damaged~ it must be replaced.
