Turbo whistling - air valve ??
« August 06, 2020, 11:16:45 »
 have developed a bad turbo whistle and lost a bit of top end power so spent yesterday with my mate and we did the following;

disconnect intercooler pipe and air filter box

attached a baked bean can where the filter box would usually be

held our hand over the intercooler pipe and inflated the system to around 15 psi to check for leaks in pipes - no issues

We then went around the exhaust gate valve which was being actuated quite frequently --> chasing the pipes towards the front of the engine we found the air vacuum / boost pressure valve and when we disconnected one of the hoses or clamped the hose the turbo whistle stopped

I have ordered a replacement part online but it seems you can't get the OEM part any more 39450-2A600

Just wondering whether anyone has had this issue and also whether replacing the part made it go away ?

If I plumb the solenoid in the "wrong" way the noise stops so my thoughts are that the solenoid isn't being triggered correctly

Just wanted to add I've tested the solenoid and that works by the way
