Cold start rattle in the turbo

[rjdelp7]

I have a slight rattle coming from the driver side turbo on cold starts. I’m thinking it is the waste-gate flapper valve in the exhaust pipe flapping like the guy says in the video in the link. Think I should live with it or use the warranty?


I’ll post a video of my Expedition doing it and add the link here.

Live with it? You have warranty. You will lose power if the waste gate not sealing/working. I would would trade it in.

Crazy these rides have such issues when there less then 5 years old with how much they cost etc. There awesome to drive when there running right though! My 2004 F-150 4x4 5.4L 3V never went into the shop the 14 years I owned it...

Man don’t let em walk on you. You e done your research, it’s time for them to step up and do their part. I just hope they don’t take your truck for a couple weeks

**Post Ford service appt: They are replacing my driver-side turbo. I was with the mechanic while he assessed the issue. Showed him the video. He said it is normal for it to make a clicking noise for 3 seconds at cold startup but not for 5 seconds or more & that he would replace it under warranty. He also listened to the passenger-side turbo which had no clicking/rattling noise.

I also asked him what common issues the 4th Gens have & he said cam phasers. That this issue normally presents its self at 12k-15k OD. Also turbos with waste-gate flapper valve issues.

You should definitely Trade it in though, it could hand grenade at any time! HAHA!

Glad they diagnosed it, and are replacing the Turbo.

Weird b/c borg warner makes the turbos, and they are a good product.

Pretty sure I have the same noises, mostly from the drivers side. But mine happens all the time, regardless of cold start or after 45min of use. I can hear it for example when there is a median on the left of my vehicle. It only happens at low RPM. Seems to mostly be on driver side, I've bought a stethoscope to listen in before I take it in. Where is the wastegate connector?

i dont think the flapper in the exhaust is a wastegate. my beemer has this issue and its a cold start emission control device that forces the exhaust gases down one pipe until it reaches operating temp when it then opens and the rattle decreases. In my 335i its controlled by a vacuum line which i sealed off as the fail safe is open. No issues with CEL or anything and no rattle now for years.

lol, please ignore my post above and sorry for wasting anyones time. i should have read the posts from the top. beemer boards are full of folks calling the exhaust flapper the "wastegate" and i just jumped. i'll see myself back to the gen 2 forum...

center, the black plastic, at the top of that is the electrical connector. If you disconnect you can diagnose if it’s the wastegate.
