Sounds like I have a vent BOV suddenly

[SetInCalifornia]

When I accelerate hard, it sounds like I have a vent to atmosphere BOV. Did a hose pop off? I have check engine light or performance issue. Just the sound that wasn’t there before.

I’m not familiar with BOV so maybe this an easy question.
Thanks

Pretty easy to check. The eCBV valve is located on the LHS of the charge air cooler. The hard plastic hose that connects to it routes around the cold charge duct and connects to the low pressure LHS turbo duct. The eCBV hose has a twist lock connection on either side.
