Sliding roof/tilting roof
Diagnosis: Ingress of water at sliding roof aperture
Ingress of water at sliding roof aperture
Cause: The sliding roof/tilting roof is installed in a water trap. The water drains off via the water trap, water drain
holes and drain hoses. The drain hoses lead downwards on both sides via the A-pillar and C-pillar. The drain
holes or drain hoses can become clogged with leaves, dirt, underbody protection and so on.

Corrective action: NOTE :
Check the water trap for leaks. Check the drain hoses for leaks and for correct connection to the water trap. Check
the drainage system for unhindered flow, and blow out with compressed air if necessary. Check the external seal
and the correct adjustment of the sliding roof.

Tailgate and Liftgate
Diagnosis: Ingress of water into rear headlining area and luggage area.
Ingress of water into rear headlining area and luggage area.
Cause: The leak problems of the tailgate and liftgate correspond to those of the doors. In addition to this, the area
to be sealed is much bigger. The routing holes for cables and hoses must also be sealed. The rubber grommets
for the routing holes must be checked for damage and correct seating (fully unhooked). The mounting points of
the tailgate and liftgate hinges may leak.
