Hopefuly someone can help me out here

When I have reds on my power steering rack solenoid is buzzing away, I disconnect the plug it goes away,

I have checked the voltage at the plug and it reads around 5v. Which according to my research is normal for when the car is stationary

It never did this before and only started doing it now, car is getting started on the weekend since we mods went on

Any way of testing if the solenoid is stuffed?

Could it be making this noise until the system is bled ? (had to remove power steering tank so I lost a lot of oil)

I gave it a temporary 12v power feed and that stopped it buzzing

Any help would be great, I don't want to have steering issues :/

It's not hard to pull off the solenoid. There are 3 Allen head bolts and a flared line coming in from the top. There are 3 o-rings sealing connections from the solenoid to the rack. You can take it down and check it off the car.

I supplied 9V to mine (it didn't seem to care of polarity) and it blocks flow through 2 of the holes (they are drilled at an angle). Blow through them and make sure they are flowing freely when not energized and also sealed totally when energized.

The hicas computer sends a pulsed voltage to this solenoid.

Maybe just air? Did you put the correct fluid back in?

I am going to use the haltech to control mine as I have removed most all of hicas.

Could be capacitors going bad in the hicas ecu

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.

      ECU sees many times the speed than speedo does (R34 swap)

      It's needed for rolling idle up, and I think it is a decider on VCT also.

      I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
