No Boost?

[Daniel4]

I have a 2003 turbo ute and its running on 12-13psi with turbosmart type1 bov and its just stopped making boost pretty much like on 5000rpm it will be at maximum on about 2-3psi. is this a problem with the standard actuator? if not what the s@!t is wrong with it?

Could be a faulty boost solenoid.

Have you tried the boost solenoid maintenance?

yeh.. does sound like the solarnoid.. try the solarnoid maintence, makes a noticble difference if never done b4

if he has the standard acuator though, wouldnt that limit his peak boost,,,,,

can you hear a hissing sound from under the bonnet, there might be a leak somewhere...... or a snake?

No worries.

Just a bit of free advice.

If you ask a question about a fault, give as much info as you can.

For example.

"My car seems to have a noise from the engine bay."

Things that you may get asked, and would be easier to diagnose your fault if info was given, could be.

1. Was it at operating temperature.

2. Under load, at idle or just free revving the engine.

3. Does it happen all the time or only some of the time.

4. What type of fuel do you use.

5. Has your car been modified, if so what components and what sort of boost pressure are you running.

6. Generic or custom tune.

And possibly many more.

Hope this helps and good luck with your fault.

1. Was it at operating temperature. when it first occurred I was changing the different tunes to see what kind of psi they had and it happened just stopped on 3 psi now ever since its been stuck on 3. (I only bought the ute 3 weeks ago too so its new for me) was at normal temperature

2. Under load, at idle or just free revving the engine. free revving the engine

3. Does it happen all the time or only some of the time. all the time since first happened

4. What type of fuel do you use. only ever use 98ron

5. Has your car been modified, if so what components and what sort of boost pressure are you running. it was on 12-13psi it has had injectors, fuel pump, 3 inch exhaust, f6 bottom end, type 1 turbosmart bov, hdi intercooler kit, crow cam valve springs,

6. Generic or custom tune.??? the guy I bought it off said it had custom tunes but both were done before and half way through doing mods but I dont think its the flashtunes because it was fine then just stopped.

And possibly many more.

Hope this helps and good luck with your fault.

I tried the solenoid maintenance now it just gets to the 3 psi alot easier haha. no mysterious noises from engine bay just not making much boost. this is all I can think of sorry mate

You might want to take it to a tuner to have a look at on the dyno then.
