Had a weird thing happen , WAs leaving my car parked and running at the bank and then I heard a loud constant PSSH sound and white smoke started coming from the drivers front corner of the hood by the abc reservoir .

I ran back to my car , turned it off and opened the hood . The PSSH sound stopped immediately when I turned the car off. I Didn't see any abc Leaks, and abc still working fine upon restart . Didn't see any coolant Leaks, coolant level and temp normal upon restart . If it was a coolant leak the noise should have persisted even after turning the car off . But the noise stopped immediately when I turned the car off . No obvious AC line Leaks and AC also worked fine on restart

also No PSSH noise returned upon restart ,and everything seems Normal!! I'm stumped !!

What could this possibly be ? Where is the intercoller pump located ? I am thinking maybe my intercoller pump or hoses failed ? (But I Checked intercoller fill cap and was still full ) car did seem a bit less powerful like I have less turbo boost now , but maybe that's in my head . Is there some turbo line or hose that could rupture and make the PSSH sound ?

any help appreciated !

OP there are too many possibilities to take a WAG at what your car is doing. Has it happened again?

A fluid leak leak will be on the ground. Coolant temperature did not go up? High side pressure in A/C goes up very fast if the radiator fan does not operate in concert with with it. Pressure sensors for A/C will store codes. Plug it in for a quick test. It should remember. If not a good tech will be able to see signs of what happened.
