Hey guys, following my DTC P2293, i replaced my HPFP since i thought my fuel pressure regulator valve/sensor was going bad.
Pressure was 1800psi at idle and everything imaginable occured. Misfires and bad performance. Now that i've changed my HPFP, the same problem occurs and i'm truly at a loss here. Wishing you guys could shine some light on my problem here hopefully.
I've linked a video of what's happening exactly.

A very high pitched noise coming from the fuel rail as well as a rough idle at all times. Let me know what you guys think of this.

While i changed my HPFP, there was no wear whatsoever. Everything was pristine.
I still get the super high pitched sort of noise though.
My specified fuel rail pressure is 20 bar, but the actual is 125 bar and i have no idea what's causing it.

I wonder if the fuel pressure relief bypass valve is clogged and not letting the excess fuel to bypass
