Bmw x3 code reader location

Bmw 2de5 code. Been having issues obtaining more than 58psi of fuel at idle on my car. Brand new module was installed and coded, new fuse, new fuel pump, new regulator, new fuel filter, new lpfs, switched back to oem backend flash nothing has helped. Only way to get it up is installing a s1 inline pump.
