[ATTACH]undefined[/ATTACH]Hello guys, i have a problem with my bmw. Got egr+dpf off and some remap, but notice a few days ago hissing sound from engine bay, even can hear inside with closed windows, outside noise is louder… i think i have boost leak but not sure, where should i check first? Sound comes only when turbo boost around 2k rpm or going up hill, on parking and accelerating there is no sound. Thanks for answers. I put video bellow u can clearly hear the sound when i press pedal. And i think i got a bit less power…
