The purpose of a return line filter is not to "save" the system, but merely to limit damage (debris in tank and damage to fuel tank / pump / etc.).
If the damage is not excessive (nothing in injectors, etc.) then the repair job will be just flushing the lines and replacement of pump --- and not flushing tank and entire fuel system.
My understanding is injectors are not replaced as part of the repair as of now.
Injectors are replaced on all VW's and Audi's, pretty sure Bosch replaces them on all failures with HPFP, to eliminate contamination issues or a needle valve sticking open caught up with debris, which on a Common rail, would burn a hole through the piston and have a runaway motor.
