any one know what this is / does
 

:confused:hi ppl i replaced all the vac pipes today with silicone ones and noticed the pipe from the turbo / actuator t piece went up to the boost solinoid then split again , one going to the boost solinoid and one going to this other thing that i know anything about . any help would be great full . thanks kev

Cant see pics but sounds like one way valve on line to carbon can.
Did you transfer restrictor pill in pipe from comp cover to t piece?
Simon

yea i made sure i put the retrictor pill into the new pipe from the old one and put it back on the compresser side . i know there is a swicth inside the car that controls the the box that the pipe goes to like its a electronic boost control or somthing . tbh im thinking of taking it of and running the pipe straight to the boost solinoid like it should be from the factory

i cant seem to get the pic up here so i have put them in my garage if that helps . soory about this

still cannot see pics, says I don't have permission to view them.

sound like boost controller from your second post but pics would help lol

after market BCS???

had a look in your garage.

It looks like a boost control solenoid but it is not plumbed in..

I would remove

Simon

i had a play with it today whilst doing the pipes . when its turned off no air will pas thru , turn it on and the air passes thru in to the engine bay . i know i gain boost when its turned on but if its not needed would it be wort taking of ?

i know its not plumbed in in the pics as i took it out to take the photos then put it all back in . thanks for ur advice tho jolly

okay that makes sense..

you could have it mapped with it on and thereforte have two boost levels?

Simon

thanks for that im going to take it off and run the pipe straight to the boost solinoid like it is as standard . manily as i dont use it any way and it sounds like its more to go wrong and id rather just have it maaped to one boost level

sounds best option
