In this case, it may be the solenoid valve dynamic specification which is at fault (atmospheric pressure
resetting time). Final fault finding is carried out by measuring this specification on a special bench.
Check that solenoid valve casing does not have any splashes of fluid on it which may impede the breather (water,
engine oil, gearbox oil, brake fluid, coolant, mud, dust, or any other substance).
Instructions:
The solenoid valve must be set up 450 mm above the ground, in an area free from water, mud, or any other fluid.
Cleaning with a high pressure jet is forbidden.
Is there coolant present?
Is the solenoid valve subjected to significant fluctuations or impacts?
Instructions:
The solenoid valve must be correctly secured to its mounting.
Contact with the engine environment is forbidden.Follow the
recommendations below.
Check the turbocharger regulation control (no
partial jamming, etc.).Follow the recommendations below.

If the noise is coming from the turbocharger, apply the Technical Note 5164A, Fault finding of noises.
Note:
Pay close attention to faulty components that might result in unjustified replacement of the turbocharger. For
example, whistling does not necessarily indicate damage to the turbocharger (this could be coming from the
exhaust, the timing, the gearbox, etc.).
