ok here goes i am trying to get a grasp of what is going on.

 

i have a TT SWb Auto and the needle never moves anywhere from 0. doesnt go - or +.

 

had turbo's checked and they are not blown and i also done the idle test and never got any smoke from the exhausts. Having had the engine checked i have been told that two wires/cables that run either side of my engine (apparently connect to turbo's) are not connected properly and so the ECU has no control over the boost :eek: apparently they were not plugged in properly and exposed to the air and have broken. been told can plug back into ecu control or get boost controller (if i can find one cheapish)

 

started worrying about over boosting luckily enough there is no boost which at this stage i would prefer than them to spool to oblivion.

 

The bit i am looking to understand is i have some sort of system that tricks the actuators into opening them longer (sounds dodgy) and a hole that restricts the boost .

 

what is this system? what does it do and what is the purpose? All i know if there is a deliberate hole made somewhere to let excess pressure escape and restricting the boost to a certain PSI. (although because of the broken wires i have no boost so this is pointless at this time)

 

 

please help me understand as whatever it is i plan to have ecu control boost again and hopefully close/weald this hole shut and have original restrictor

Sound like what you talking about is a manual bleed valve, not reliable and it wants removing.

 

The standard boost solerniods work in much the same way and are controlled by the ecu. If they are unplugged the will remain shut so you should be running actuator or saftey boost (about 5psi).

 

Sounds like you have the added complcation of someone adding a bleed valve so this is why they will have unplugged the solerniods.

 

I'd put it back to stock and also fit an aftermarket boost gauge so you can see whats going on. The stock boost gaiuges are rubbish and also electric from a sender in the engine bay so its probably just not reading rather than your car not boosting at all.

is this an easy job? apart from the stock gauge

 

cheers bud

Have you got an extra bleed valve somewhere then (should have one on the pipe to the actuator for each turbo really) or just the stock solerniods?

 

I unplugged my solerniods as had a pro spec b controller fitted and when it went on the rollers we found that the ecu was getting confused and you only want one system electronically controlling the boost.

Unfortunately i have no idea. i have no boosty controller (electrical) as far as i have been told so far the two solenoids are rusty and where they were exposed won;t work... although it looks like they were just pulled half out and tightened.. wonder if i can try putting them back in?

 

all i know is i hear a whistle when i accelerate (which sounds like the hole) but short of someone actually showing me i am lost. having someone look at it later but i will just go and take a photo of the solenoids now.

ok got the photos to what i believe are the solenoids

 

 

 

 

 

 

do you reckon these would still work ? is this the way they are meant to be or are they meant to slot in further?

 

cheers

Hi mate, they're not solonoids, solonoids are in essence an eletro mechanical switch, in this case they'll open to release boost pressure to avoid over boosting (stand to me be corrected as I'm still learning) they are possibly boost jets? Some one will able to say for sure though. As said in a previous thread, get it checked by an expert, they'll be able to tell you what needs to be done to get it running correctly...

ok lol i guess when i was showed i must of not understood ^^

 

cheers
