Hi all,

My engine won't boost at all. The second it goes above 0 Bar it blows off all the pressure.
No DTC at all and no CEL.
I attached a video showing me tring to boost and the sound of the blow.
I will appreciate any ideas what to check.

Thanks all

Boost leak. Should be easy to find, since it's major. First check the hoses to the intake on the front of the engine. The Y-hose to the throttle body often splits at the hose clamp. Check the bypass valves and all hoses to and from intercoolers. If you can't find it build a boost leak tester and keep digging. Instructions for boost leak tester can be found by searching the forum.

Check the throttle body boot to see if it has come loose or if it has a tear. Needs to be removed to properly inspect. They crack on the bottom a;d cannot be seen unless removed.
