Two problems related to tail light switch have been reported for the 2004 BMW X3. The most recently reported issues are listed below.
The lamps in the rear tail light assembly do not work. The connection is corroded. Similar item was under a recall for 2002-05 3 series sedans (BMW recall campaign 11v-438) and this X3 shares many components with the sedan. The lighting assembly/connector is suspected to be one of them.
While I am driving the instrument cluster light turn off, all digital display on cluster disappeared about 10 seconds and turn back on. It seem like all headlight and tail light also turn off. It seem like happened 1 or 2 times a year.
