When my 406 HDI 110 engine shutdown after running, there is a hissing (like vacuum noise) from the turbo solenoid for a few minutes and gone. Also sound goes when I disconnect feeds from the solenoid. and also when pressing brake pedal few times after engine shutdown vacuum hissing stops. This vacuum is from turbo solenoid feed of brake master side. is it normal? EML not flashing any error. Should I be worried. Please help.

There's usually a fair bit of hissing as the fuel pressure releases, Not sure about the vacuum system but you might be hearing that too.

This is from Turbo solenoid valve.

MY bro's old 110 did it all the time. Never did find out why but it didn't cause any problems either.
