Question:

I installed a retrofit TCU from a 2009 335 into my 2008 328i.
No problem with the install, one Blue connector is not hooked up to the TCU because the TCU I got only has 3 ports,
regardless, the Bluetooth worked without coding. Everything is working well. I just randomly was trying out all combos on the MOST connector bus to get it into the loop.

Only thing I have an issue with now is a SOS malfunction light. I don't have an SOS system in my car, nor do I have BMW assist in my car.
Any ideas on how to remove this error? Should I start with the green wires and remove or re-arrange them? Does it have to be coded out?

Also, do I need to code the Bluetooth since its working already? like update the software?

Thanks in advance!
