Hey guys, I'm stumped on this car. Wanted to see if I could get advice. Car isn't producing boost.
2007 e92 335i

Replaced: Valve cover & gasket, boost solenoids, all vacuum lines, cones filters, charge pipe, bov, spark plugs, ignition coils, fuel sensor, vacuum canisters & hpfp

Cleaned up injectors and intercooler as well.
Inspected all piping related

It starts and drives fine but just doesn't produce any boost. If I step on hard for a seconds it will hit limp mode. No mhd or jb4. ISTA showed 30FF, 30FC & 5E18 codes.

Any ideas?

Are your waste gates stuck open? Does the exhaust seem louder than usual when trying to build boost?

Stepped on the gas and looked at the arm & it moves fine. Couldn't see the front arm though.
I received the car like this so I can't tell about the exhaust sound.

How would I go about getting a log? It doesn't have any jb4/mhd/cobb.

If u have a fbo your gonna want a monitor service. I'd highly suggest you get MHD it's going to help you from chasing around in circles. I'm guessing you have no access to a vacuum pump either. Pull off the vacuum lines on the boost solenoid that go to the turbos. Suck on them you should be able to hear them move. That'll rule out stuck open wastegates. doubt that's the issue though.
