Strange issue, the ambient leds in all doors, cupholder led and the stereo surround LEDs are not working. Checked the factory fitted connector which hooks up to the stereo surround led, which in turn has a y cable for the cupholder led. There is power coming through the factory fitted ambient light connector and you can see a very faint orange glow for the cupholder led, it’s barely visible but is there. It’s like there is not enough power going through, any ideas anyone ?

Hello, I have exactly the same problem! were you able to solve it? I have a doubt about the FEM box.:confus2

I solved this issue by connecting ISTA to the car, the memory fault codes were full, which in turn caused failure of certain interior LEDs, the ac surround, door card LEDs and the down light LED on the cupholder. Once I cleared the memory fault everything worked again. Hope this helps
