Model Description
X5 Sports Activity Vehicle

Production Date
From Start of Production (SoP)

SITUATION
Moisture in the driver footwell and/or passenger footwell when the air conditioning (A/C) is activated.

CAUSE
1. The condensation water drainage hose of the air conditioning system is not routed correctly, blocked, or
not connected correctly.
2. The floor of the heating and air-conditioning unit could be broken.

CORRECTION
Correct drainage hose routing / connection or replace. Ensure there is no blockage.
Replace HVAC box.

PROCEDURE
1. First, make sure that the moisture has not
entered the footwell through the slide/tilt
sunroof or the front doorpanels.
If this can be ruled out, check the condensation
drainage hose of the air conditioning system
and the housing of the heating and airconditioning unit.
Check the condensation water drainage hose
of the air conditioning system for correct routing
and connection.
Closely examine the connection point just
above the center tunnel (centrally below the
instrument panel) and reconnected if
necessary.
If the condensation water drainage hose is
damaged, replace it.
Pictured is the correct installation of the drain
hose.

2. Here the drain hose is folded over and will
require replacement to seal properly.

3. Here the drain hose is incorrectly installed
and will require replacement to seal properly.

4. Check the housing of the heating and air-conditioning unit (in the areas which are visible) for cracks.
If cracks are visible, replace the heating and air-conditioning unit.
5. Once the repair is complete, run the A/C on the fresh air setting to generate condensate and ensure the
drain flows properly. If drain is not flowing, check for foreign objects stuck in the HVAC box which could be
blocking the drain.
6. Finally, dry the damp area of the carpet and reassess the vehicle.
