Weird turbo noise

[nick0360]

Maybe it's just me being anal but when truck is cold I got a weird wine from the turbo when spooling, it goes away when truck is up to temp should I be worried? Also I was working under truck today right after shutting it off and noticed a noise every 30 seconds or so like some sort of electronics were still up and running last for about 5 minutes keys outta ignition too like I said maybe I'm just thinking into it to much but I don't know, oh and it's a 2012 6.7 with 33k

I also have the weird electronics noise coming from under the cab once and awhile after it is shut off. At first I thought it was related to the dpf but all that is gone and it still does it once and a great while at random.

Woah definitely not that, its faint just sounds like something is still getting power some sort of electronic but that's all, anyone have the weird turbo whine while driving truck cold?

correct me if im wrong, but im almost positave thats the turbo vanes being closed your hearing during your first warm up especially if its cold out, it aids quicker engine heat, have a listen to you exhaust ( if your deleted) it should sound like a jet, once the motor is up to temp the exhaust pitch will change to more if a rumble and the whining and odd turbo sound will go away.... when i first heard mine a few years ago i was worried.... then i started playing deteciave its completely normal.

It's not the turbo vanes, it is the wastegate solenoid. Mine did it and was replaced and is doing it again after 15K.

how hard is the wastegate solenoid to replace because mine is doing the same thing

That sound in the video isn't normal, I should have been more clear I was answering some one else's question, my bad lol about a weird turbo whine while cold
