Default not spraying on boost

I've had the system in my car now two years car is a 2007 audi A4 2.0T
Lately the fail safe has been kicking on when I step on the gas I'm getting no water in tank when tank is full led on gauge
Power drops off and car goes limp and system no longer sprays on boost
Recently installed new fav any help would be Great amazing even

Do a "SYS" test. Let me know if it sprays.

Do not unhook the 6mm, need to know if it sprays after the FAV, unhook the 4mm hose from the jet instead.

So I'll try this this weekend it's been a busy work week for me
So it started to work then stopped now it's working again spraying on Boost... I'm running straight distilled water for right now but the level is going down.
I know something is still wrong it didn't just fix itself. I find that very odd because nothing changed that I did from the time that it wasn't working to the time that it started to work again.

I await your test results on post#4.

Why did you replace the FAV?

Ok so I tried below with 4mm removed after fav.
Hf3 board made a clicking sound then lights on Gauge water level, water injection came on yellow no spray after multiple blips.
Also tried moving fav jumper to sys and no spray
" Activate the system by F-IDC:
a. Set the far left trimmer to fully counter-clockwise.
Crank the engine and leave it to idle, you should see
the blinking green led on the controller board.
b. Blip the accelerator paddle sharply to induce an
artificial load. The amber led should respond. A faint
but noticeable spray should develop at the jet."

If you move the FAV jumper to SYS, you have virtually disabled the FAV. Ifr want tyo do the SYS test, use the spare PRK jumper.

I found another issue the water level sensor in the tank was actually spinning. I thought that might have been cauing my issue but after I adjusted and road tested same issue persists.
Going back out in a min to try and see if I can get water past the fav
