INPA not showing fuel pressure

[Rick3]

Hello, when i accelerate my car (E60 525i LCI N53) the car gives a shock and goes into safe mode and half engine light goes on sometimes.

So i got INPA and read the error codes, and it give error code 29F2 HPFP minimum pressure fallen below.


When i want to check the fuel pressure in INPA, this is just empty and not showing, how can i get INPA to show me the fuel pressure?
it has to be on the right side on row 5 and 6.



I hope someone can help me.

Hi, did you get Inpa to show fuel pressure readings??
My copy is exactly the same even after updating the SP DATEN E89 files.

Suffering from low fuel pressure but trying to figure out if its LPFP or HPFP

Hi, i did not mannage to show the fuel pressure.
But i got all the injectors out and cleaned the tips, and replaced the high pressure fuel pump did resolve te problem.

I also changed the fuel filter but i dont think that was the problem.
If u pull out the injectors make sure u put them in back at the exact same location.
