ok, but it still could be bad, take off the little hose to the tank where the cap is located. with the motor running, you should see good flow.

VR6 engines don't have the pump impeller problem... at least that I have seen.

Plugged heater core.

I had a Jetta that flow tested good, but once I took the core apart it was obvious that it was bypassing.

With a bad impeller yes.... but I don't think that is your issue.

I'm guessing the core is bad.

Took me a while to correct my VR6 mistake... sorry.

Your Passat as you know has a V6, the VR6 was only available in the Jetta. Golf & Touareg.

I type too fast some times!

I have not seen loose plastic impellers on the V6 or the VR6 motors.
