Subject: Having problem with X3 light system Author: rlduncan : member since January, 2008 : 6 posts Posted on: 2010-05-19 22:19:39

I have a 2007 X3 that has a problem with the lights. With the ignition off and the key out, the front parking lights, rear taillights and the halos around the headlights stay ON all the time unless you disconnect the battery.

With the ignition ON and the car running the parking lights, headlights and left side turn signals run all the time. The highbeam indicator is also ON. None of the switches can control any of the lights (headlight switch, high beam switch, turn signal switch), however the hazard flasher switch will cause the four way flash function i.e. the right side turn signals also flash.

I diagnosed it to be the Light Control Switch (LCZ or LCM) module. Replacing this did not correct the problem.

Is there another component that would cause this problem?
