Xdrive control module replacement

Tcheb · 01-03-2020, 10:34 AM

I'm replacing the xdrive control module on my e91 xdrive. The passenger footwell got flooded and i'm suspecting the module fried while sitting in water.

Do I just connect the new module and that's it? Or do I need to program anything to get the car to "accept" the new module?

Thanks!

did you ever resolve? i had the EXACT same issue with flooding due to clogged sunroof drain. i'm hoping i can plug and play a used module.

If you don't get a response here, it would be an easy enough question for the guys in the coding sub-forum to answer

i already answer in a other post, but to complete the post here i will answer:

hi,

To answer to your question, VTG unit is not plug and play, you will need to run ISTA-D to :
-Transfer old data from clutch wear from old VTG unit to "new" one
-reset classification resistor
-Calibration

AND if your car is manual and you get an VTG unit from automatic car, you will need to apply your current VO data to the VTG unit with NCSExpert ( FA_Write) because VTG will send communication/limp mod error with transmission data not receive
