Transfer box coding?

Hi all,
I don't know if anyone can shed any light on this?
After fitting a recon transfer box/servomotor I am informed that it needs coding to the car?
Has anyone heard of this or does it sound rubbish!

Not rubbish. Did you get a resistor included in your reman. unit?

If so, either the adaptions or something else need re-setting to recognize that resistor.

If you remove that resistor and replace it with the one from your old unit, then (I think) no coding required.

if ya gonna do it do it right

Transfer case adaptations resets with DIS 57
FYI ....see post number two in this link .....this is the "function selection" page you work to in DIS 57 for the transfer case (VTG in BMW speak) adaptations resets


DIS is a weird and wonderful software from days gone by but it does function albeit slowly and deliberately....be patient when you push the selection buttons....they can have some hang and or hold time

after you get to the function selection page and have highlighted the VTG line from "service function" ....then ...."drive".....to select VTG.....it will give you a couple of options ....one is "repair" and the other "change oil" .....or similar verbiage ....these will show in the third column on the right of the pane....again ....be patient with the buttons....it likes a hand with a slow touch as the song says

click on oil change .....it may not seem as if anything has happened....but if you go to the pane bottom and click on test schedule it will pop up a pane that has your selection of oil change on a single line .....click on this line item of "oil change"

click the green arrow at screen bottom right and it will lead you thru a reset adaptations process that take maybe 30 or so seconds

if its quiet around you its easy to hear the actuator doing its thing....let's hope all our transfer case oil change diy'ers can migrate to resetting the transfer case adaptations without angst
