So I was having some problem with my front passenger side turn signal, and after I took it to a shop I decided to buy an used LCM IV and give it a shot...

Here's the problem:

With Original LCM IV:
The front passenger side turn signal will not light up, no matter what I do(turn,hazard, etc). No error message. Everything else works fine.
Seems like the LCM unit has lost all contact with the front passenger side turn signal.

With the used LCM IV I bought:
The front passenger side turn signal work perfectly fine, but the front xenon headlight will flicker, or goes on and off from time to time.
The 'check low-beam light' message comes and goes. Sometimes the Xenon light will flicker, sometimes it will turn off/on suddenly, and sometimes it will work perfectly fine.

The LCM IV I bought does show a different HW version and SW version, however it is also pulled from a 2004 X5. Both are 'LCM IV Without LWR'.


I'm thinking that maybe both LCM IV units are faulty, or maybe the ground wire, or light socket is causing the problem with the newly purchased LCM. (Maybe because the original LCM lost contact with some of the lights, and therefore not detecting the issue that's causing the flickering with the new LCM)

Anyone had similar issues before?
