Oxygen Sensor Heater

Hello,
I have a 2014 BMW x1 x28i and i am getting the engine malfunction warning which puts the car into limp mode. This only happens after i have run the car for a few minutes and it's hot. If it's a cold start, the car runs normal. I hooked it up to the carly app and i get the following codes:


Engine / Motor
:Lambda probe before catalyst temperature
Code: 002CAA
Charge pressure control, shutdown: pressure build-locked
Code: 002C58
sorry, unknown fault
Code: 002CA4

I just replaced both o2 sensors and that did not solve the problem. I can't find any information on the oxygen sensor heater circuit for this car. Can anyone help with this?

thanks in advance,
Scott
