Was having a general check around under the bonnet last night and noticed a stray unconnected hose coming from the bottom connection on what I believe to be the boost solenoid.

Here



Does it connect to this?

Yes it does .

Cheers. Mark.

Thanks mate

Is that black box on the inlet just a resonator? I'm tempted to get rid of it because it gets in the way!

Yes resonator.

I disagree that the connection on the 3port boost solenoid is connected to the resonator though..

I suspect you have traced the hose into the mass of hoses incorrectly.

top connection to pressure side of turbo, middle connection to actuator, bottom connection is a vent and is connected to the resonator.

The unconnected pipe in the picture is running from the bottom of the solenoid.

I was hoping that as it was disconnected that was the reason for my backing off when flooring the throttle occasionaly. Is it a problem for that pipe to be disconnected?

excellent.. my misunderstanding the picture then.

the pipe being disconnected is not a problem with regard to the boost solenoid.. the problem will be that the hole left in the resonator will be sucking in unmetered air.. therefore the maf voltage will be reduced and the ecu will run more ignition and less fuel.

Thanks for clearing that up m8.

Any info on backing off and feeling like it doesn't want to accelerate when planting the throttle lol

That's the next thing I need to sort out now

The hose should also have a brass restrictor fitted inside, just passed the 9-0 degree bend..
This helps control boost spikes and IIRC has a 2mm hole in it.

I am going to clean the solenoid this evening as long as it's not raining so will see if the restrictor is in place. Could it have fallen out or is it bonded into the hose?

it cannot fall out.. the pipe is narrower than the restrictor.. ie. it is stuck in the pipe.

scoobykevuk

is the restrictor in the above pipe?? the one that goes to resonator? what will happen if its missing? cheers (sorry to hijack lol)

Scott.T

Yes should be in the pipe that returns the air to the resonator.

likely to over boost if missing

But only if decatted. It probably won't overboost if the cats are still in.
