I have a 2003 X5 that I had in the UK. There were fog lights in the rear, before shipping the truck to the US, they converted it, however they lefted the Light Control Module switch with the two fog light switches in.

Now when I turn on my signal light in either direction, the opposite side light under the reverse light will light up and flash as well, so it looks like I’m going left, but the right side of the car underneath the reverse light flashes as well. I have replace the LCM with a used one with the one fog light button, but this did not fix it.

Any ever see this and solved it?
