Hi everyone,
I was hoping someone could help me diagnose this problem. I have a 2011 N55 xdrive and got the dreaded reduced power mode warning. I pulled the 2e0f (valvetronic system deactivated, adjustment fault too frequent)and 2c57 ( Charge pressure control, plausibility: Pressure too low) codes simultaneously.
Car runs smooth, maybe a small drop in power.

Any ideas on where I should start looking? I tried googling each code but I wasn't sure how they relate.

Thanks in advance.
