I just did some more work with NCSexpert and it says I already have FRM3 as my NFRM module. But from what I understand a fresh FRM would work better for the retrofit hence why BMW say it is neccasary.
If you could do me a big favour, could you take a photo or draw a diagram of the connecter on your new light harness and post it here?
The reason is that I think it is quite different to what I have with my wiring setup. That retrofit pdf a few pages back seems to only have a wire on Pin 1, 2, 5, 6 and 9 to 11. So pins 3 and 4 arent needed, according to that bmw .pdf
I think it might be
pin 1 - tagfahrlicht - AEs
pin 2 - ground
Pins 3 + 4 ????
Pin 5 - Xenon
Pin 6 - Shutter???
9-11 blinkers etc.
Hopefully if that is the case, the retrofit harness should sort out the flickering. removing pins 3 and 4 might be a good test.
EDIT: This what the retrofit instructions suggest the wiring connection must look like.
This is a bit weird as there is no pin 6 on my xenon headlamp connection but there is one on the car/frm side
