I have a X1 2014. I was driving to the tire shop and everything was fine. Got my tires on and headed to get some food, everything still fine. My brother takes my car to go to work and calls me saying the car is being all funny, I ran the codes and I got:

2c57
2906

I’ve checked hoses and clamps and stuff everything seems to be in good shape. When driving there’s a loud whistle boost noise kinda. car is in limp mode too I think.

Could anyone guide me in like how to properly check and what specifically to check. I’ve looked all over online but it hasn’t been much help.

Thank you.
