Faulty fuel pump?

How long ago was the fuel filter housing replaced, could these issues be connected?

The fuel filter housing was changed back in January ..

Did you ever fixed the issue?

Fault code clearly points to fuel quantity valve... low pressure codes are because malfunctioning valve.

I changed the y94 qcv few days ago but still same faults car drove fine...When i connect the leak off tester i see that i get alot of compression leak in bottles with foming forming...I guess that injectors are faulty cause today its barely running with 130bars on idle and no gas response at all.
