Default 2012 STI wastegate selenoid issues

Hello everyone,
Im new to this forum, and recently bought a 2012 sti. I absolutely love the car, but it recently threw out code p0425 for the wastegate solenoid "a" low. I have talked to many tuners around my area, and they have told me it could be an issue with the Aquamist kit(previous owner installed). I am in desperate need of help and would greatly appreciate any help on this issue if anyone has experienced it before. Thank you!.

Have you tried the DR1 link?

I was able to get into the module, and in fact the DR was not set to 1 so I went ahead and did that. Will test it out and let you know if I keep getting the same issue. Also, besides the DR being set to 1, is there anything else I need to set correctly in that module?

Just one step at a time. DR1 should override the CEL.

Hello Richard!,
So the CEL problem got fixed and the meth injection was running perfectly until recent. Every time I hit boost the "water level" "water injection" lights turn on and no bars on the gauge light up. also, the "b" light blinks rapidly every time I hit boost. i would greatly appreciate any advice on what to do in regards to this issue. Thank you for your time!

From your description, it is obvious to me what is happening.

The cause of issue is quite clear, if the system is triggered (B led) and receives no flow signal from the flow sensor (bars display), it will trigger the failsafe (yellew led).

The system is doing exactly what it is designed to do.

You need to track down the delivery line from the pump to the jet.

So I ran the lines and I saw that the jet that sprays to the top mount intercooler was actually broken. So I think we found the problem, but I'm not too sure as to where I go from here. Is there any way to just buy that specific part ?
