Transfer case actuator motor

[sv1cec]

OK I know this is an old thread, but please don't yell at me. I have a problem and I need an answer by tomorrow morning, so please allow me to ask.

I have discovered a faulty connector to the resistor on my transfer case actuator motor. The connector is broken and the wires some times make contact but some times they do not. So I get an error in my error memory.

A local BMW shop has a new resistor and they are going to replace it for me, but I've read somewhere, that the resistor has to be programmed in the car, using DIS/GT1. Unfortunately, the electrician of that shop is on vacation and the owner told me that programming the resistor is NOT necessary.

For those of you who have changed your resistor or your actuator motor, how important is the programming of the resistor in the car? In other words, what will happen if the resistor is not programmed?

Many thanks for your attention and sorry for reviving an old thread.
