63 M156 engine noise after turn off
Hello Guys tell me what that hisses on my C63 M156? Maybe someone had a sound like that on your m156.
I think the sound is from the intake manifold. Sound like air.
What is that noise. After turn off the car?

One of the symptoms for a bad PCV is a hissing sound after shutdown. This might be your issue.
Depending on the mileage and age, many choose to replace the intake manifold gaskets, bolts and the PCV valve at the same time as a preventive maintenance.
Good luck.
