E90 ZKW projector bowl retrofit- My progression...
Ok folks, I've been doing a ton of research on this and trying to find the best way to retrofit my lights as my output is horrible. Well, I'm going to take my time, do it VERY slowly so as to make sure I document and capture every detail. From there, hopefully, I can do some sort of a DIY/write up for others... I was only able to find a few pictures on E46f, so hopefully I can make something a little more informative to others...
So, I've heard that the E90 retrofit is nice because there are no electrical modifications as all parts are ZKW... But, the E90 cars use a D1S bulb as opposed to our D2S bulb, so from what I understand, mounting and securing the bulb will be a bit different. I'll learn more about this as I go. For now, I kept the projector, bulb securing bracket and the lens (who knows, maybe I can sell them on eBay)...
First step is to acquire E90 projectors. I found a drivers headlight housing with busted tabs on eBay for $70 shipped. I picked that up and then had to get the projector bowl out. This turned out to be a massive challenge as I found ZERO write-ups, you tube vids, or info ANYWHERE on this, so after a few hours of prying and poking at the thing, I got frustrated... Pics show my results...
But, after a few hours of some intense jigsaw action and prying, I finally got down to what I needed. I feel really bad hacking up some OEM parts, but it was a busted unit already and not of interest on eBay from what I could see. Plus, I got what I needed, no damages to those parts, so I'm happy. As you can see, the projector bowl is in perfect shape, and it is metal, so hopefully this retrofit will be a forever fix. I need to get new bulbs, but I'm going to wait until I get my OEM lights out and apart. I'll have to see if there's a way to fit the D2S bulb in there or if I will need to buy new D1S bulbs..
