DIY: E9X ACC Retrofit

Marv17 - i don t remember, i swapped everything that was missing on my board. follow also the lines from the LEDs, you might find other parts you are missing

Has anyone else had issues adding the LDM to their car?

ACC shows up fine on the module tree, but the LDM is not showing up, I verified wakeup signal voltage and that it has power coming from my fuse tap. CAN wires are connected with PT-CAN high and PT-CAN low being connected properly. I'm using the terminal 15 wakeup signal for all modules but it seems like people have also had success using the dedicated ACC wakeup signal. I tried both and it still doesn't show up, not that I can see how it makes a difference swapping wakeup lines.
I ordered a new LDM to test with since they're cheap but I was wondering if these modules fail commonly or if there's something I did wrong here. Considering I wired up the radar properly I can't see how I did anything wrong here after checking 100x and I'm assuming I just got a dead module.

Tried with a new LDM and my car still doesn't recognize it.
Does anyone else have any ideas?

100% sure it's wired correctly. I used a CAN to USB adapter I had and I'm able to receive CAN data from my wiring.

What junction box rev do I need? I did try a junction box I had lying around from when I was building a test bench but I had no success with it. The junction box was from May 2007 and my car was built in September 2006.

That is old , you don t have the proper junction box

Do you know which one I need then? RealOEM only says that junction boxes up to 09/2007 are compatible with my car. So it seems like if I get one later than that then I'll have to start rewiring things.

It does not make sense to me that you could order a 2006 E90 with ACC but my JBE does not support it despite being newer.

realoem story is old, i won t explain it now

get M junction box

you might need to change more parts on the car and get to the new type of junction box instead of the old typa junction box
