Customer states:
 They see a water drip from the
headliner area (Figure 1).
Figure 1. Water intrusion near the headliner.
Technical Background
One or a combination of the following four possible scenarios may be present. All of the following areas of the
sunroof system will need to be inspected as possible root causes, and if applicable, each may need to be
modified or corrected.
1. Sunroof drain hose or outlet valve:
Using the VAS6620 Sunroof Drain
Snake follow the cleaning
procedure for the sunroof water
drain hoses as described in
ElsaPro. Any possible obstruction
other than debris cleared by this
procedure will be apparent after
this check such as a kinked or
pinched drain hose (Figure 2).

2. Roof opening seal:
Inspect the entire perimeter of the
roof opening seal for any possible
detachment or malformation
(Figure 3).

3. Glass sunroof panels:
Check all adjustment axes of the
sunroof glass panels for poor
adjustment (Figure 4).
Figure 4. Front and rear glass panel adjustment.
4. Unexplained or unduplicated water entry:
When the vehicle is exposed to water (rain, car wash, or standing water on the roof panel) either with the
vehicle stationary or driving it is possible for water to enter the sunroof frame, breach the normal water
drainage channeling, and leak into the cabin area, particularly if the sunroof is opened or vented when the
vehicle is wet.

Any possible water drip may not
appear until after a driving period
when the water travels to the
underside of the headliner area
during the normal course of driving
(Figures 5-7). This may occur due
to a slow migration of water along
the wind deflector hinge arms and
potential water entry into the
stowage area for the wind
deflector. This stowage area does
not provide water drainage away
from the vehicle.

Production Solution
Solutions have been implemented in production.
Service
The instructions that follow are service solutions that, when performed accurately and completely, are effective
in stopping water intrusion and help to avoid unnecessary parts replacements and repeat repairs. All of the
possible root causes described here will need to be fully addressed and any necessary repairs completed prior
to releasing the vehicle.
1.
Sunroof drain hose or outlet valve:
Ensure that any water in the sunroof frame drainage areas flows freely after the cleaning procedure. If any
obstruction is due to a pinched or kinked drain hose the damaged drain hose(s) or valve(s) must be
replaced.
2.
Roof opening seal:
If after inspecting the roof opening seal any detachment, malformation or damage is discovered, replace the
sunroof opening seal.
3.
Glass sunroof panels:
If after all dimensional measurements are made on the sunroof glass panels an issue is found make the
necessary adjustments to the sunroof glass panels.
4.
Water entry for what appears to be through the sunroof frame:
It is not necessary to replace the sunroof frame unless there is damage found (e.g. crack in the drainage
structure, hole in the drainage structure). If damage to the sunroof frame is found, clearly mark the area of
damage. Sunroof frames replaced for damage will be requested for return to AoA for analysis.
Note:
In analysis a complete leak test of the sunroof frame will be conducted. If the results of this test reveal no water
leak in the sunroof frame including the area marked as damaged the sunroof frame will be returned and the
claim for the frame replacement debited. If no damage to the sunroof frame structure is found, then proceed as
follows.

5.
Open the front sunroof panel
completely and locate the
mounting points for the sunroof
wind deflector (Figure 8).
Figure 8. Locating points for the sunroof wind deflector.
6.
There has been a design change
to the wind deflector to enhance
the water flow and drainage in the
event the wind deflector gets wet.
Inspect the area of the wind
deflector shown (Figure 9). The
redesigned wind deflector has
small tabs cast into the deflector
structure on both sides. If the
wind deflector does not have
these tabs replace the wind
deflector. Make certain that the
replacement wind deflector
contains these tabs before
installation. With the redesigned
wind deflector installed, proceed
as follows.
Figure 9. Tabs cast into the redesigned wind deflector.
7.
Using a primer applicator D 009
500 25 (or equivalent) and D 009
401 04 all purpose cleaner (or
equivalent) thoroughly clean the
area shown (Figure 10). It should
be free of any lubricant or
contaminants and completely dry. Figure 10. Area of sunroof frame to be cleaned.

8.
Cut two 25mm strips of AKL 450
005 05 Butyl adhesive/sealing
cord. Firmly press each strip into
the groove shown (Figure 11).
Both channels shown in the cut
away must be completely filled
with the butyl cord.
Figure 11. Preparation and application of butyl cord.
9.
Next, a modification will be made
to the sunroof glass panel (Figure
12) by bonding two small pads to
the front corners just inside the
rubber ‘skirt’. The purpose of this
modification is to create a gap
between the ‘skirt’ and the
sunroof mechanism beside it, and
as a result, prevent water from
making contact with the sunroof
mechanism and possibly
breaching the water channels.
Figure 12. Area of sunroof glass panel to be modified.
10. Clean the inside surface of the
glass panel ‘skirt’ using D 009 401
04 all purpose cleaner (or
equivalent) and a clean dry cloth
as shown (Figure 13).
Figure 13. Area of glass panel ‘skirt’ to be cleaned and dried.
11. Apply D 355 205 A2 Bonding
Agent using a primer applicator D
009 500 25 (or equivalent). Allow
bonding agent to thoroughly dry
(Figure 14).
Figure 14. Area of glass panel ‘skirt’ where bonding agent is to be
applied.

drawing is included to illustrate
the precise positioning of each
pad from the inside (Figure 16).

14. Using a 3356 roller tool (or

(~50 Nm) to the newly adhered
pads to enhance the strength of
adhesion (Figure 17).
