Guys please help! This is so frustrating. I continually pop these codes almost instantly after beginning to drive the car. Kicks limp mode and reduces the turbos. These codes began to pop after replacing the HPFP if that changes anything. I’ve bought brand new bmw knock sensors from the dealership and no fix to the codes. Anyone?

Since you have replaced the sensors, what's left is a wiring issue or a DME problem. DME rarely fails, at least not this way. Here's the wiring diagram:

Pull off the X60005 connector at the DME and measure continuity of the wires to the sensor plugs. You may have injured the wiring during your HPFP replacement
