After following this thread for months, I've finally was able to get euro tail lights working for my G82 M4, US spec.
Parts:
- About 120 ft of 18 AWG Wire
- 12 X connector pins (61138369696) (I ordered 20 from my local dealer since they come in packs of 10)
- 1 X Euro light switch with rear fog button (61319461141 or 61319461142)
- A set of euro tail lights or equivalent, I used a set of aftermarket GTS tail lights
Unlike the G20/G80's the G82 is wired up for brake/turn signal with a single wire. To get euro tail lights, I had to wire up the following connects to the BDC board in the passenger footwell: (LEFT is driver side, RIGHT is Passenger Side)
- RIGHT OUTER LIGHT (PIN 4) -> BDC A58*5B (PIN 19)
- RIGHT INNER (PIN 4) -> BDC A258*3B (PIN 50)
- RIGHT INNER (PIN 1) -> BDC A258*5B (PIN 20)
- LEFT INNER (PIN 4) -> BDC A258*3B (PIN 38)
- LEFT INNER (PIN 1) -> BDC A258*5B (PIN 12) (right hand drive fog lights)
- LEFT OUTER (PIN 4) -> BDC A258*5B (PIN 11)
The hard part of the whole wiring part is the actually put the pins in the socket, I've definitely mangled some of the connect trying to fit the pins. I only know about the connector pins (61138369696) that
larrylam646 posted in the an earlier post and it seems to be bit bigger then the OE pins for the outer light connecters. I've try to find the right pins with no luck but was able to make the connector pins work with some patience. Those pins are gonna be a tight fit for all the connects, (inner tail lights and BDC board) but the biggest thing is to take your time, make sure your crimps are good and making good solid connection with the wire.
For dual fog lights, I wired both the fog lights together and connected it to pin 20 and now I have dual rear fog lights.
Don't forget to install the euro light switch, it was kinda hard to pop it out, just take your time and work around the perimeter with a trim removal tool. This switch is plug and play.
I've attach some wiring diagrams that helped me with my install. I'll try to attach some photos of the progress.
Now to the coding, I tried
TTG bimmercode coding and I wasn't able to get the inner turn signals to work and I also get hyper flashing but I was a good starting point for sure. Unfortunately I had to bust out the laptop with Esys and Bimmerutlity. I changed my vehicle type code from "43AZ" to "41AZ" (LHD EUROPE) and then coded the BDC_BODY3. And voila, everything is now working! I have working euro turn signals, and fog lights.
I understand that not everyone have access to Esys.
TTG 's instruction is almost there and I think its the LIC_VERSION_DATA that would have done it for me if I had know what was. This is my LIC_VERSION_DATA:
wert_33 (DD,14,0B,0C,8A,3E,01,4F,00,0A,14,02,B4,C8,02,F0,0 F,41,D4,2C,27,32,03,03,07,02,6C,78,3F,EF,16,0C,04, 0A,27,0F,77)
I am going to attach the NCD comparison result for NCD 5665 and 7083 so anyone can feel free to see what changes a euro car has vs a us spec car in BDC. I'll also attach the actual NCD if that can help (might even help with anti-dazzle coding?)
Now if I had to do it over again, I'm not sure if it's 100% worth it, but I was a fun learning process, understanding how it works behind the scenes. I mean who uses turn signals anyway?
