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
