Problem with Rear Right Taillight – Possible LCM Issue?

[Spunbearing]

Hey guys,

I was hoping someone might have some insight or have had a similar issue to what I am currently seeing with the rear taillight on my X5. I have had the problem before with either a melted plastic housing or a burn through hole in the metal but this is a new one for me. From what I can tell the light housing is working correctly and when bench tested all the lights work but when it is installed in the vehicle the bottom light refuses to light up. There is no corrosion on the connector to the light and we have not had any water issues. Has anyone had their Light Control Module fail in this manner? Is there a possible fray point for the wires? My understanding is that the LCM has to ‘detect’ the light otherwise it will not turn it on and throw a warning but the contacts are clean, the bulb is new and it works on the bench.

I am going to check the continuity of the line going to the taillight from the LCM this week but I wanted to see if anyone had seen this before. I thought it was going to be a quick fix but it looks like it isn’t. Any help would be great, thanks.
