I found the VIN from the old car and the TCU is from a 3L X3. As the tcu was manufactured 26.9.2005, the wiring from such a car should be:

(edit)

Sadly its the same wiring

Triple-check that you have +12V on pins 17 & 18, Ground on pins pins 36 & 54, and ~+7V on pin 15. Do this with the TCU removed and triple-check that you have the pins identified correctly. If the TCU has +12V, ground, and I-Bus, then the Telephone option will appear on your nav menu or MID.

In my experience helping people with TCU/ULF retrofits, mot of the problems are due to a wiring fault in the adapter harness, and only a few are a bad component. So, assume that your wiring is bad and work from there. If you do the triple-check and still get no results, then maybe you have a bad TCU.

i will scope the IBUS signal tomorrow morning.

Ibus is connected and alive -> TCU is dead.

Short update: i bought an 2006 ULF, plugged it in and it works fine.

just one little problem, which pins at the 18pin connector need to be connected to simulate the pairing button? i was not able to find it at the wiring diagrams

As usual CCJF1 to the rescue.

I think you GND the pair button, test it with a meter to see if it's idle low or high then pull it the other way.

Yup, you ground the pairing pin to initiate pairing.

thanks alot, but got it sorted with the unnamed bmw software

I have '05 330i that didn't come with assist or navigation. I've installed a TCU, Bluetooth antenna, and microphone. The TCU is part # 84106965056. I've verified online that this unit should work with an e46. I can't get my car to detect the TCU in DIS, INPA, or NCSexpert. I've verified that my wire harness is configured for US TCU-Everest, not BIT. According to WDS pins 17 & 18 are constant power from the battery. When I test those wires I get less than 1v. Can someone test pins 17 & 18 and tell me how much voltage you are getting? Or is there a resource that shows how much voltage each wire is supposed to be getting? Any help would be greatly appreciated.
