Every time I turn off the 718 it makes the noise just behind my door in engine area. My guess is fuel pump depressurizing but want to know if any of you hear this too? Not sure how to upload video for sound.

Is it a short sound?

That we have talked about before.
After a drive shutdown and lock your car, wait 30m and then unlock/lock your car and there is a big chance your gonna hear that sound again.
(if we are talking about the same sound)

The 718s make a variety of sounds as systems shut down, for as long as several minutes.

I think the Enterprise had the same 'feature' .

Yes probably 3 seconds. It will happen again if I start the car and shut it off, hence I was thinking it's the fuel pump being relieved.

Found the issue... Turbo wastegate valve !

 

[cbarra]

Issue? Or just cause of noise?

 

[rico]

Cause of noise and a issue, need to replace the wastegate by a new one.

Can you tell me more? I’ve suspected a wastegate issue on my Cayman S. Did Porsche diagnose the issue? Are you under warranty? New turbo?

 

[rico]

Yes correct I have warranty extension so nothing to.pay, not new turbo only the actuator.
