Re: Pump starts then stops within a second. MKVI GTI - HFS-4
Where is pump located?
Once the failsafe triggered, the idc will reduce as the signal drop below the trigger point. When you said the pump stopped, was it physically stop or stop flowing fluid?

The pump starts (pumping sound starts) and then it goes quiet. I remember clearly in one of my repairs last year, I kept the rear seat unfolded to hear if the pump was working. And I'm 100% sure that once it starts it doesnt go quiet until I take my foot off the pedal. |

When you did the "SYS" test, did it go quiet?
This is most puzzling. The pump is switched on by a relay, either all on or all off. Can you change the relay and see if it cure the problem. It is just a single 4-pin automotive type relay.

If you unplug the red harness, disabling the FAV you can run the pump as long as you like.
I like you a this test if possible, unplug the 4mm hose from the jet and let it spray freeing outside the engine. With the red harness reinstated, run the SYS for 30 seconds, tell me if the fluid flows out freely.

One more possibility...
If the water filter is clogged, you will get this problem as the fluid started to flow. See if you can purge the system by disconnecting the 6mm from the FAV and observe the flow of the water during "SYS" activation.

That is this relay made of? They should be no more than 5 dollars!
