F85 X5M Drivetrain Mulfunction-No Misfire

[bydz]

Hi,

I have a drivetrain malfunction that appears when I’m in sport mode and accelerating hard. The car is idling fine. BMW has not been able to accurately trace the fault. They say they got a code that looks like charge pressure or something like that and replaced some hoses to the turbos that were cracked. The turbos themselves are fine and the air mass flow sensors are also fine. There was a bit of oil near one of the inter oilers but they say that isn’t the issue. Can someone please help point in the right direction.
