Hi guys. Was driving my d22 3.0l turbo and went it hit boost someone went bang and then my turbo started squealing when hitting boost. Ant ideas?

I reckon when your zd30 hit a boost, the impact of this has caused the unnamed person to explode, in turn the turbo has seen this and started sqealing in terror, while also being hit by boost which only made it more frightened.

Ps. Probly an intake hose split or boost sensor line popped off

+1million on the first answer that's perfect!!

+1 on the second answer it's more logical

Check if the EGR pipe has a crack or hole in it, i have heard a few that have done that and caused the same symptoms as you describe.
You may need to pull the pipe off the engine to check it properly.

its a pita to check but yea nathan is right the EGR pipes by this time in their lives are prone to cracking, an easy way is look for soot on clean paint but its not always easy to see.

Check your turbo!

+1 on the egr pipes.
Happened to mine, didnt hear and bang though. Cut the cracked sections of pipe off and it was job done. I had the engine warning light come on too.
