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.

NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
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? Follow the recommendations below.
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.).
Does the turbocharger control work? Carry out the necessary repairs.
Replace the solenoid valve.
If the fault is still present, contact the Techline.
