REcent VTG transfer Case repair followed by DSC malfunction and VTG BMW F25

[Milosek]

Hi There,

I do have F25 automat, 3D 85000km, 3 months ago I had my VTG transfer case repaired. No replacement just repair of current case. After service I picked up the car and noticed that is not behave as 4X4 something was weird it was not so ,, flexible,, as usually even fuel consumptionn raised up.

Month ago when we got to winter seasoon and roads got frozen and slippery my feelings were assured that something is wrong, for example on roundabout I pushed throttle /pedal little more and the car started drifting, there was no reaction from DSC system.
During the drift I could add the pedal more and more with full power. Even the DSC warning light on ON-Board computer was not switching on nor any attempt from ABS. There was absolutely no attempt to stabilize the traction. Hence went back to service to runn diagnostic via ISTA+.

It showed DSC and VTG and ICM were highligted in YELLOW and I attach picture to this thread what the diagnostic showed.

There was VTG and DSC and ICM error codes with same description of the problem. But i dont really understaand what that mean nor the guys in service were confused. Can you help me to get whsat is the issue please? I guess bad calibration of the VTG?[IMG]/Users/milostrpisovsky/Downloads/IMG_0482.jpg[/IMG]
