Sunroof / Moonroof Drain: All Technical Service Bulletins
Headliner - Stained

Group: 60

Number: 01-01

Date: June 7, 2001

Subject:
Headliner, Stained

Model(s):
A8, A8L, S8

All

Condition

-

Water leaks and stains headliner near A-pillar (arrows) and C-pillar trim.

This may be caused by pinched, kinked, restricted, incorrectly-routed, or disconnected sunroof drain hoses. Any of these conditions could cause
insufficient water drainage, forcing water to back up, and resulting in a leak.

Service

-

Disassemble headliner and A- and D-pillar trim to access sunroof drain hoses. See Repair Manual, Repair Group 70, Interior Trim for detailed
information.

WARNING!

Observe safety regulations when performing work on or near airbags (see Repair Group 69 in Repair Manual).

-

Water-test roof and check for leakage into vehicle interior around sunroof drain attachments.

Note:

^

Water may overflow from catch trays due to drain hose restriction.

^

Expansion foam in A- and D-pillars can change the drain hose cross-section from a round to an elliptical shape, restricting drainage.

^

The rear hose can become pinched by the rear bumper.
