Foul Odor when Switching On A/C
MODEL

F48 (X1)

Vehicles produced to February 05, 2016

SITUATION

May be a foul smell (musty, rotten, and vinegary) when the A/C is first turned on that lasts about
five minutes.Micro-filter position too low in the IHKA housing.
CAUSE

Micro-filter position too low in the IHKA housing.
CORRECTION

NOTE: Replacing the evaporator will not rectify the problem!
z

Restore proper drainage flow from the evaporator and replace micro-filters.

z

Raise the position of the micro-filters with respect to the IHKA housing.

PROCEDURE

1. Check for proper alignment/ clearance for condensate drain:
Exterior (under vehicle)
• The exhaust heat shield must not squash or damage the protruding condensate drain hose.
• There must be clearance between the heat shield and the drain.
Interior
• Remove the driver and passenger side trims. (REP 51 45 …) (Included in 64 31 010)
• Check, from the side, whether the condensate drain is seated correctly against the A/Chousing (deformed/rolled/flipped at the top). The flange must be sealed uniformly around the
drain hole of the A/C housing.
• Check if there is any saturation of the carpet from water around the drain.
• If deformation of the drain is seen or water damage to the carpet then the condensate drain
must be replaced. Lower the exhaust and heat shield to access the A/C drain.
2. Remove the micro-filters from the IHKA housing (REP 64 31 010).

3. Clean the evaporator and housing using BMW lance/wand (83 30 2 413 653) with Spray Gun
from SATA USA.
• Dealer can order the gun directly from SATA and receive a 25% discount for a limited
time.
• Item #11072 – HRS Undercoat gun, Type 1, without wands.
• Payment method - Credit card
• Contact - via telephone at 800-533-8016
• Email - [email protected] or [email protected]
Use Repair Instructions 64 51 001 with the approved BMW Group products in the parts list
below.
4. Self-flush the evaporator by parking the vehicle outdoors and let it run for 12 minutes with
the A/C on and the windows open. The resulting condensation will flush out any remaining
contaminants. If you are in a low humidity environment, flush the evaporator and housing
with water using the BMW lance/wand.
5. Modify the new lower micro-filter, with hot glue gun and glue sticks (previously provided
for BMW crash pads) according to description below, to provide offsets on the bottom, to
prevent wicking of the water into the filter. NOTE-the old filter can be used as a future
template for the hot glue dimensions.

All 3 hot glue applications must be double layered, be 15 mm long and have a total height of 4-5
mm. Placement of the hot glue must be in the exact locations shown to prevent complications with
condensate water flow.

6. Allow the applied glue time to dry, then install the upper and lower micro-filters in the
housing (REP 64 31 010).
