I still have the turbo vane rattle/fart on my 05 6.0 F350. Sometime ago I made a video tape which is available at the URL given below. If you listen closely, you can hear the noise. "wa pah pah pah" and then me saying "there". Local Ford says not to worry. I think it's abnormal and am of the mind right now to take out my frustrations at Bitterroot Ford if in the future I find out, I need a new $2000 turbo caused by this problem. The movie is in .mpg format and 9 mb in size

tsb--06-3-11 this article supersedes 06-3-11 to update the vehicle model years 2005-2006. some 2005-2006 f-super duty vehicles equipped with a 6.0l engine may exhibit a buck/jerk condition in low(L), first(1), or second(2nd) in manual transmission vehicles, or in manual 1st, manual second, or in tow-haul mode in first(1st) or second(2nd) on automatic transmission vehicles. this concern occurs anywhere from 1800-2500 rpm at steady throttle or slight tip in. concern will be more evident under a load, or while pulling a trailer. this concern is more noticeable in manual transmission equipped vehicles. ACTION--reprogram the powertrain control module (pcm) to the latest calibration using wds release b41.11 and higher or b42.1 and higher. this new calibration is not included in the b42 cd. calibration files may also be obtained at www.motorcraft.com

I have the same problem on my '05 F250, but without the fart. I had started a forum chain about this named "intermittent turbo spool-ups." I noticed that the problem only occurs when hauling 600lbs or more. And it's intermittent. I've only noticed it in automatic. I first experienced it while going up a hill and towing my quad and some other camping equipment. I'm afraid I'm going to have to take it in... something I did not want to do as I do not want my firmware reflashed.

larryj50 nice video ! got the same noises but every! time i get off the throttle, and get this.... when i complained and went for a test drive with the area rep and service advisor, dealer/owner/shop tech, they state that is normal for the 6.0. all 4 turbo`s that they have replaced make the same noises, but mine will do it till i`m almost down to 50 kms/hr. it gets kinda annoyying when you hear it every day (99%) highway driving here. not tomention how loud it is. ( 05 f350 cc 4x4 ). both our other 05`s trucks never did this.

my truck does the same thing , and it is not turbo fart.. only does it if I am accelerating slightly , the truck will jerk at about a 1 second interval and I can hear the air noise coming from under the hood.. as soon as I push the accelerator down enough to downshift it stops .. only does it in high gear...

Exact same symptoms
My truck is making the exact same sound from the turbo. While under load going up a hill and I let off coming into a corner it will make three quick "coughs" or "belching" sounds from the intake area of the engine. I posted a thread last night describing my issue and asking for advise. My truck is a stock '04 with 16,000 miles. I've never taken it to the dealer for the problem...it has never been flashed or changed from day one. So do I live with it, or is there a solution? My biggest concern is engine or turbo damage. I'm open to suggestions!

From What I Understand Turbo Fart Occurs Any Time That The Turbo Is Spooled Up And You Suddenly Let Off The Throttle, It Is Basically All The Air That Is Forced To Suddenly Slow Down In The Intercooler... I Believe That This Is Completely Normal.. Mine Does That As Well.. But Also Does The Jerking Under Slight Acceleration Without Accelerating Enough To Downshift.. And It Is Worse With A Bigger Load..

I've had two "re-programs" done and the latest Ford recall "re-program" for the exhaust on my '05 F250. I still have the same "problem" sound occurring. Plus be careful if filling up the diesel tank using a high volumn truck stop style pump. Not sure if it puts too much air in the tank, but my truck coughed and bucked for about 5 miles after that fill up. Never happens when using a lower volumn car style pump. Thoughts, is it trapped air and looses prime ?

Cough Update - Problem Fixed
Took my truck in to the dealer with trailer attached. Their diesel doctor rode with me with his portable computer. Up a hill at 65 mph, truck coughed, computer said EGR valve. Back to shop, they replaced the EGR (said the old one was "all crudded up", highly technical term), back for a test drive and all seems to be OK. Hope y'all have the same simple problem. I was as 35,905 miles, just under the 36K warranty limit.
Their tech also demonstrated the "turbo fart" some of you have described. He did it on one of the other trucks in the shop. Completely different sound and symptom. He did say that one was normal.

What year is your truck?

My truck also does this if it has the programming in it or stock. My truck will completely lose boost while climbing a long grade with a load i have to let out then ease back into the throotle to get it to build back. Also if I hammer it for 300 yards then let out then get back on the throttle it blows smoke bad and takes 3-4 seconds to build boost. I believe we all have the same problem STICKING TURBO VANES!!!

J. Lauer - Mine is a 2004, completely stock. Replacing the EGR seems to have corrected the problem. I had also noticed some smoke when under load even if it was not "coughing" at the time. That seems to have gone away also.
If you are having a similar problem, a new EGR valve is a simple fix. Mechanic was under the hood for about 5 minutes.

Mine has had a new egr valve, a new vgt solenoid, a new back pressure sensor, and been reflashed 3 times. Someday they'll replace the turbo or maybe I'll just get a 06 thinking that is going to be the surefire way to fix it.
