SITUATION
The surface is peeling off one or more of the IHKA operating panel buttons, and the button symbol may become unreadable.2010 BMW 750Li (F02) V84.4L Turbo (N63)
Page 465
CAUSE
Ingredients in certain skin care products, including sunscreens and hand lotions, causes the button surface to peel.
In the picture, you can clearly see how the low fan speed button is just starting to peel. Two of the four fan blades are missing from the
button symbol, and soon the entire symbol will be gone.
[NEW] PROCEDURE
Improved replacement buttons for the IHKA panel are now available as a kit.
Refer to ETK for the correct part number for your model. Replace ALL the buttons included in the kit.
Note:
The repair procedure can be performed inside the car without removing the console or control panel.
1. Use two narrow picks to carefully pry off the button caps. Since the button will be replaced, pay special attention not to damage the
switch.

There are two types of button switches; a rocker type for the fan speed adjustment, and a regular pushbutton type for the others.
2. In this picture, the fan speed button cap has been removed. The cap is attached to the two individual square openings of the switch
3. In this picture, the driver's side seat heating button is being removed. The cap is attached by four retaining tabs; two on the top, and
two on the bottom. Remove the two top tabs, and then the two bottom tabs.
4. The cap has been removed, and the four retaining tabs can be seen.
5. After all button caps have been removed, install the new caps by aligning them squarely to the switch, and then pushing in firmly.
Working from the center outward will simplify the installation. After the first cap is installed, check for functionality and smooth
operation before installing the next cap. Continue installing the remaining caps in the same fashion.
