Hi! I have been trying to fix my car for a month now. 30FF came on and took the car to a local bmw / german car shop.

VRSF Chargepipe, TiAL BoV, VRSF Dual Cone

Whenever I accelerate it sounds like the BOV is blowing PS PS PS PS PS PS PS whenever boost is being generated, usually bigger, in city accelerations.

They said they smoke tested the car and there was a small crack on the turbo outlet. I ordered VRSF Aluminium one and they replaced it. Car acted the same. They had the vehicle for another week and a half, they said my problem will be the blow off valve.

Ordered a new one, still having the same issue.

They said the smoked the vacuum lines twice, didn't find any problem.

Here is what's it sounds like

No other codes being shown other than 30FF
Car goes limp on heavier (50%-70%) Throttle

No tune.
