Quad HID Bi-Xenon Projector retrofit

[Spools]

So I bought my first BMW a few months ago. 2009 135i with H7 halogen reflector high Beams and H7 halogen projector for the low beams. Headlight washer was removed. No auto leveling or adaptive headlight components. The guy I bought the car from said the high beams don't work. He wasn't sure why. I'm not quite sure how to diagnose the problem either. The car also gave a warning light for the washer tank being out (missing).. i think There's two warnings I got. One was everytime the car was started and the otherjust randomly. I think that one was for the Adaptive headlights. He said he just never got around to coding that out. Guess he didn't know how to do it in Expert mode. Sometimes I'd get another warning light

I'm not impressed with the lighting of the low beams anyway. I have a pair of Morimoto MiniH1 6.0's and also a pair of NHK G5-EX (3.0" lens) still in the box along with Diode Dynamics RGB Demon Eyes, reflectors, ballast, butyl rubber, etc... I just put in a $700 order with The Retrofit Source for an H7 D2S Elite HID Kit (XB55 D2S 50w ballast, Osram 6200k 55w Night Breaker D2S bulbs and PWM Canbus Relay harness,) H7 high beam splitters, H1 bulbs, Profile RGB Demon Eyes, Profile 80mm RGBW angel eyes, BMW door logo projector for the doors (was on sale for $15, so i had to get it,) etc...

So I've had my headlights open for a couple weeks now so I need to get it back together soon. I'm using the reflector. I painted it anodized red over the chrome. Installing the MH1's in the high beam mounted via the threaded shaft and the G5-EX's in where the OEM halogen projector went. I had to do plenty of trimming of the bowl and the backside to get it to fit.
Both will have RGB Demon Eyes and I'm still utilizing the OEM angel eyes. They have a crisp white DRL LED board from Depo. I've been searching for an RGBW or switchback DRL board, but can't seem to find one at all.
Installing the 80mm RGBW angelneyes over the front of the Gaitling Gun Shroud over the MH1's.
Not utilizing a shroud for the G5-EX's, because I can't fit one from the front since the projector is mounted to the reflector shroud from behind. I want to use my own shroud, but can't seem to find a retrofit bracket for these headlights. I'm thinking I'll have to finally buy a 3D printer and learn how to operate it and the software and make my own. I have a set of Panamera 2.0 Switchback shrouds painted in red anodized with the Profile Pixel RGBW+Switchback Amber LED insert.

I'll be using two H7 HID relay harnesses. One for the D2S and the other for the MH1's. High beam splitters from the BMW H7 high beam bulb plug on each side. Each harness has one H7 input. One harness will go to H7 input and the other harness with get the other side's low beam H7 input for signal.

Will I run into any issues with these working? What about coding? Any idea where I can get a retrofit bracket for these headlights?

I'll post pictures of my progress in a couple of days. Thanks

Any updates on this? After dealing with the incompetent boneheads at Bav groupe designs, I almost want to learn to diy retrofit lights so I’m never dependent on someone so terrible again.

The depot lights etc are really cheap, would they make a good base for practicing? Is the housing good but the internals suck, or do the whole depot housings have issues?

Please update this, I hope it’s coming along great for you.
