How to identify the failure of your turbo
This problem analysis allows you to more easily determine the origin of a malfunction in the turbocharger. Keep in mind that in the event of a turbocharger malfunction, the turbocharger should be considered a component of the engine block. The damage may indeed be more extensive than you might have thought in the first place.
Follow the steps of this problem analysis one by one: you will most likely find the answer to your question.

Turbocharger check
Dismantling the pipe connecting the air filter to the turbocharger makes it possible to feel the clearance of the rotor. If the radial play is such that the wheels rub against the housing, the wear of the turbocharger is excessive. We advise you to replace the turbocharger immediately. If the play is not excessive, proceed to the next step
Erratic turbocharger noise
Clogged air intake between air filter and turbocharger
A clogged air intake/filter prevents normal air intake from the turbocharger. This leads to the creation of a depression, which causes year oil leak at the level of the turbocharger. This oil leak reaches the compressor wheel, which causes a resonance effect due to the high speed of the turbocharger.
Air supply to turbocharger clogged
A clogged air intake/filter prevents normal air intake from the turbocharger. This leads to the creation of a depression, which causes year oil leak at the level of the turbocharger. This oil leak reaches the compressor wheel, which causes a resonance effect due to the high speed of the turbocharger.
Contaminated turbocharger compressor side
The presence of impurities on the compressor side prevents the turbocharger from sucking in air freely. This leads to the creation of a depression, which causes year oil leak at the level of the turbocharger. This oil leak reaches the compressor wheel, which causes a resonance effect due to the high speed of the turbocharger.
Excessive turbocharger noise

Air leak at the duct between the air filter and the turbocharger
An air leak can cause oil to leak from the turbocharger. This oil leak reaches the compressor wheel, which causes a resonance effect due to the high speed of the turbocharger. The flow of air escaping to the outside via the orifice of the leak also emits a hissing sound.
Air leak between intake manifold and cylinder head
An air leak can cause oil to leak from the turbocharger. This oil leak reaches the compressor wheel, which causes a resonance effect due to the high speed of the turbocharger. The flow of air escaping to the outside via the orifice of the leak also emits a hissing sound.
Air leak between turbocharger and intake manifold
An air leak can cause oil to leak from the turbocharger. This oil leak reaches the compressor wheel, which causes a resonance effect due to the high speed of the turbocharger. The flow of air escaping to the outside via the orifice of the leak also emits a hissing sound.
Exhaust gas leak between cylinder head and exhaust manifold
The exhaust gases escaping to the outside emit a hissing sound due to the speed of the gas flow.
Exhaust gas leak between exhaust manifold and turbocharger
The exhaust gases escaping to the outside emit a hissing sound due to the speed of the flow
