    Does anyone know what group on VCDS is for checking pressure for pump in tank? I m search but cant find, maybe is not possible to check this?

    Car on stage 2+ work fully normal and on stage 3 problems start, before stage 3 on car was added turbo hybrid, injectors RS3 ( 8V ), RS4 relife valve and DW65 pump in tank
