Need Help with Transfer Case Reset

I've been having a shudder issue with my car for months (http://www.e90post.com/forums/showthread.php?t=1201992). I've ordered a new transfer case motor (27107546671) and am going to install it on Saturday.

I've been told I will need to reset/code something with the transfer case as the new motor will be sending new voltages and the computer needs to know how to interpret them.

My questions is, can someone walk me through the steps on how to do this or show me the DIY? I did a search and came up with nothing.

This is the software I have - INPA, NCS-Expert, Tool32 and WinKFP.

Thanks in advance!

I can't walk you through the steps as I no longer own an AWD E90...

The VTG module is the transfer case control unit (VGSG); Verteiler Getriebe Steuergerät. To access it in INPA, go to E90 -> Transmission -> Gearbox / DXC VGSG

You should be able to default code it with NCS-Expert and calibrate it with INPA. Hope that helps, good luck.

I am brand new to coding, so a bit weary. Not really sure how to "default code it with NCS-Expert" or "calibrate it with INPA"

Can anyone expand on this? Other people have told me this cannot be done with INPA and that DIS.. something.. has to be installed.

Or perhaps let me know in more detail how to reset the transfer case for the new motor?

Again, I no longer own an AWD E90...from memory, I believe it's <F6> Activate and then <F5> Calibration..........

So I went into INPA and to E90 -> Transmission -> Gearbox / DXC VGSG and did some translating. I hit F5 (calibrate) and F5 (calibrate), but it didn't look like it was doing anything after I got there.

Also not sure what needs to be done with NCS_Expert.

This thread is saying that the reset can only be done with DIS software - http://www.bimmerfest.com/forums/sho...d.php?t=818073

Is that true?

It may have been at one point in time, features/capabilities directly correlate with software releases.

In any case, DIS is ancient dealer software. You would be best off pursuing the current dealer software, ISTA/D. Sometimes referred to as Rheingold.

Perhaps it's worth considering a handheld scanner:

With regards to coding...

I did do some searching on coding the transfer case last night and didn't come across anything helpful. I did some coding with NCS_expert yesterday and sucessfully coded some options (folding mirrors, windows up/down with fob, etc) using the BMW coding tool. So I know what to do, I just need to know what ECU module (CAS, FRM, KOMBI, etc) and what the line item is and what to change it to.

I guess I need to figure out ISTA/D...
