2008 X6 4x4 ABS DSC EBV failure

[cbx79]

Hey all,

I've got a 2008 X6 35D with 90k on the clock. I hit the errors mentioned when rapidly accelerating from standstill, almost without fail the errors will pop up on my screen. Once the car is moving past 25 mph, then I can floor it and I wont get the errors, its only when accelerating from standstill and rapidly. If I accelerate gently, then I have no issues and the car drives fine.

Quick searching shows speed sensor issues and changing Transfer Case oil but is there anything else it could be? I've already changed the transfer case servo motor, that didn't resolve the issue. On another note, my Auto Hold throws an error and doesn't work. Could the DSC module be causing this issue? I have staggered tyres, 315/35/20 rear and 245/40/20 front if that helps.

Any ideas on what the issue could be before I take it in to an indy?
