Technical Background
One or a combination of the following four possible scenarios may be present. These areas of the sunroof
system will need to be inspected as possible root causes.
1. Sunroof drain hose or outlet
valve:
Visually inspect all 4 sunroof
drain hoses and valves for any
damage or obstruction (Figure 2).

2. Roof opening seal:
Inspect the entire perimeter of
the roof opening seal for any
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. This is heightened if the sunroof is opened or
vented when the vehicle is wet.

This 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 occurs due to a slow
migration of water along the wind
deflector hinge arms and water
entry into the stowage area for
the wind deflector. This stowage
area does not provide water
drainage away from the vehicle.

Production Solution
Production solutions have been implemented in production. The instructions that follow are service solutions
that, when performed accurately and completely, are effective in stopping water intrusion and helps to avoid
unnecessary parts replacements.

Service
1.

Sunroof drain hose or outlet valve:
Ensure that any water in the sunroof frame drainage areas flows freely. Replace any pinched or
otherwise obstructed drain hose(s) or valve(s).

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 a problem 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. If no damage to the sunroof frame structure is found, 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

Figure 9. Tabs cast into the redesigned wind deflector.

contains these tabs before
installation. With the
redesigned wind deflector
installed, proceed as follows.

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.
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.

equivalent) and a clean dry cloth
as shown (Figure 13).
