Hi everybody,
I was driving my car on full boost ,0.8bar.
Suddenly i heard like bang, car lost power and wont boost over 0.2bar.Car is running good under boost though, no smoke no rattle etc...
I checked ic piping, all good.
Dump valve is ok too.
The wastegate is a genuine tial f38 i bought 6 years ago.
Can a bad diaphragm cause boost leak or on the contrary i should overboost as the valve wont open.
I m confused because my friend says a bad Diaphragm can cause boost leak.
Can it be the turbo itself? I say again no whislte no smoke at exhaust.
