There is an outside temperature/direction display on the headliner. Mine seems to have stopped displaying the information although if I press the LED display, it comes on but fades when I release the pressure. Any ideas? Thanks!

It should be possible to test the sensors with an ohmmeter (I think) as they will likely be temperature sensitive resistors or thermistors.
Testing the voltage was the thing to do in the old days of analogue and direct current systems but I think you will find the electronics on your car is digitally based and difficult or impossible to test with an ordinary meter. An oscilloscope will probably be needed...
There are two fuses one in the right I/P junction block an one in the left I/P junction block ! The right is marked DK / RKE 10amp fuse. The left is marked A/C / CRUSE 10amp fuse ! I don't think these are the problem ! These fuses supply power to the microprocessor in the driver information center . According to my service information the microprocessor supply's power to the ambient air temperature sensor an to the compass.
This mode displays an 8 point compass heading on the left hand side of the DIC. The compass will display the current vehicle direction relative to one of 8 compass headings using N, NE, E, SE, S, SW, W, and NW for the readout. The ambient temperature displays on the right hand side of the DIC. If the ambient temperature is below 3?°C (37?°F), the temperature reading will toggle between displaying the outside temperature and the word ICE for two minutes. If the temperature is less than minus 40?°F for more than 2 seconds, OC will display. If the temperature is above 140?°F for more than 2 seconds, SC will be displayed. If OC or SC is displayed DTC's will be set. For compass calibration and compass magnetic variation adjustment refer to Electronic Compass Calibration .
not sure about that one but there is a dimmer wheel by the light switch. move it up and down to dim and brighten the dask lights/cluster. wheel may need replacing. also work the lights on and off switch manually to see if there every thing works smooth or hopes from dim to brite.
The outside air temperature indicator's displayed temperature can be recalibrated. Press and hold the reset select button for 10 seconds . While you continue to hold the button, the display will scroll through temperature settings from +3 to -3. When the desired correction value appears on the display, release the button, and the recalibrated outside air temperature will be displayed. Each time a desired correction value is entered, it replaces the previous value. Give that a try mmkayyy:)
Hi Dale. Look under the front bumper either on the left or right trim panel. The trim panels are triangle in shape. An outside temp sensor usually sits in this area. The sensor may be missing. BMW has the sensor, wire, and connector available sperately if they are missing or damaged. It will cause the outside reading to be -40 and can cause the a/c compressor not to operate.
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located
below the speedometer in the instrument panel cluster.
The DIC buttons are located on the instrument panel,
to the left of the instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected. The bottom line of the DIC shows the
shift lever position indicator. See Automatic
Transmission Operation on page 3-23 for more
information.
If your vehicle’s DIC has these features, the compass
direction and the outside air temperature may also
display on the DIC when viewing the trip and fuel
information. The compass direction appears on the top
right corner of the DIC display. The outside air
temperature automatically appears in the bottom right
corner of the DIC display. If there is a problem with the
system that controls the temperature display, the
numbers will be replaced with dashes. If this occurs,
have the vehicle serviced by your dealer/retailer.
The DIC also allows some features to be customized.
See DIC Vehicle Customization on page 4-66 for
more information.

the sensor is located in front of radiator if you open hood and look down behind front bumper you should see it, or look from under the frt bumper, it easy to change, also get part from dealer it not $$,hope this helps.
The exterior temperature display is built into the Automatic temperature control unit. or the A/C controls. Look at the buttons for the A/C unit and press the one that is marked "EXT". This will display the outside temperature.
