Fuel injection error

[E53_ped]

Hi all been looking on this forum for a while decided to join .

I have a 2003 x5 3.0 diesel having issue with it fuel injection system error on dash I've tried a few things

Changed fuel pressure sensor on the rail for genuine Bosch

Changed fuel filter

Cleaned the in tank pump filter mesh

Still getting this error on hard acceleration car goes in limp mode

I have scanned and had it scanned and get error regarding fuel pressure controller Egr is sorted I tried to blank off vacuum pipe but didn't core issue so that's gone now the code that is

Any help would be great

Couple of quick questions for you... is the car an LCI (facelift) model - the facelift change was in Sept 2003?

What was the error code(s) on the scan.

It sounds like a fuel delivery issue but that just a guess at this point...

Mines pre facelift code is 1190 I'm using BMW scanner China clone to read code

As you likely already know...

1190 - DDE: Rail-pressure plausibility

Checked the in-tank fuel pump is working properly? To check this is tricky but you need about 2.0-3.5bar of pressure at the fuel filter inlet.

Im going to test that but maybe difficult due to error resetting when engine turned off .

Pre-facelift M57 has supply pressure sensor on top of the fuel filter. Check the supply pressure first with diagnostics, should be near 4 bar. If it drops on load below 3 bar it will also cause low rail pressure (usually caused by inline fuel pump).

Is the engine starting normally (so not indicating a leaky injector)?

Will check that . No starting issues at all

Thank you for reply all have helped in other items to check
