Model Description
X5 Sports Activity Vehicle

X5 M Sports Activity Vehicle

Production Date
From Start of Production (SOP)

SITUATION
Customer states that they always hear a whistle (air noise) coming from the rear B pillar vent(s) when the
vent is in the closed position.
When the vent(s) are fully open, or the air output is set to the footwell position then the noise goes away.

CAUSE
Air leaks from the junction between the B pillar duct and the B pillar vent. This air leak can be heard if the
vent slats are closed.

CORRECTION
Apply felt tape around the B pillar vent to close the air gap to the B pillar duct.

PROCEDURE
To confirm this issue, put the blower motor on highest setting for face vents and close B pillar vents. If
whistle noise is heard from the B pillar vents, then remove the lower B pillar trim panel to access the vent
assembly.
Follow Repair Instruction 51 43 150 Removing and installing/replacing trim panel for left or right door pillar
(bottom).
Separate the vent assembly from the ductwork.
NOTE: The vent is referred to as Grille in the repair instructions
Wrap a single layer of felt tape
(61 13 6 920 760) around the B pillar vent.
The felt should seal any air gap between the
vent and the duct.
If noise came from both sides of the vehicle,
then repeat this repair on the opposite side B
pillar vent.

If the ductwork has split or the air gap is not
closed 100% with the felt tape on the vent
alone, apply a secondary wrap of felt tape
(54 34 7 248 700) around the junction of the
duct and vent assembly.
Reassemble and retest.
