Hi
I have 2010 e90 320d n47 177 hp engine and have very weired problem engine replaced with used because of siuzed bearings. After replacing engine without any error engine cut fuel after 2500 rpm and unpress acceleration pedal and press again car again acceleration till to 2500 rpm all value seem normal I checked low pressure pump high pressure pump , rail pressure regulator hp pump quality valve every think about fuel system looks like normal and car doesn’t give any error code during and after this problem . Also checked ecu and flashed stock and tried with used another ecu same 
So anybody have experience or suggestion about this issue

Did you mount original low pressure fuel lines?

There is difference in how they run depending on injector variants.

Hi

check dpf

Dpf deleted and emptied

Katalizator still exists? Try without DPF or check on ISTA exaust pressure before DPF/katalizator. Maximum allowable pressure 0,5 Bar, better 0,2 Bar.
