Hello guys , I am working on BMW X6 E71 2008 3.5d..
Problem is with DSC , all lights on dash are on(4x4 , dsc , active steering,airbag,RPA,parking brake...) also WIPERS are on and no control over them.
I read errors with ISTA and there is a lot of "message problem" transmitter DSC reciver ICM , EMF , MRS, AFS..

The weirdest thing:

There is no communication with dsc UNTIL  I press the brake pedal , when I do that all dash lights are gone and no errors.
Also when fault lights are on AUTO Hold is lighted green , when I press brake light is off ... When I move steering wheel dash light and auto hold light are lighting on my movment (blinkning ).

What did I try: 
JBE replace
SZL replace
ICM replace
AFS replace
Checked all fuses 
Replace fuse box
Checked ground connectors in engine bay 
Replace brake light switch
Replace steering wheel angle
Checked FCan wires to DSC
(I didnt left any of this parts on car , I just test it because I have used car parts shop)

This problem firstly come when you steer to full stop and drive  and not always , now it is only good when you press brake pedal

Anyone did have this and know what is problem ??
