Well I finally am getting mine fixed. Called Ford Customer Service and kept talking to the next supervisor. After the 4th one finally got someone to listen to me after saying the standard "its normal". Its somewhat humerous to listen to their reasons for the noise, most had never heard the noise and are just people there to put out fires. Good luck to all and I would say be persistant. Squeeky wheel gets most grease.

 

Keep us posted if the replacement part solves the problem.

will do, probably will start back up at some time. But I hope I no longer own it then

 

Ford Rep on another thread collecting information on this problem.

 

Its about time the looked into it!!! Also my replaced part fixed the problem. At least for now.

 

Had mine done on a trip to Texas before they started denying the problem. Had about 20,000 miles then, currently at 58,000 and still good. Maybe just a bad batch.......

 

To all you guys thinking about letting it ride, take it from me, don't do it. I've got a decked out 2011 F250 that just about eats my lunch every month on the payment. I've kept up with maintenance thoroughly and mine started making this noise at about 58,000 miles and I let it ride on the advice of a few mechanics I know well. Bad decision. I now have 74,000 miles and my turbo has gone from humming to howling, and I'm sick about it. I could've fixed it for less than $200 dollars and now due to long-term reduced airflow in my turbo, despite how small the leak was... Well my turbo got too hot. It's still running ok, but the life of my turbo is very limited now and I still don't even have a check engine light. The ONLY light I have ever had is tire pressure... Man oh man. Now what?

 

--------------------------------------------------------------------------------
I just got back from the dealer to have my truck serviced and I asked about this issue. The chief mechanic has a 2011 F250 as well and his truck is doing the same thing.

He referred me to TSB 13-10-7 with lays out the issue and the troubleshooting procedure for the tech guys. He told me it is an annoyance and that his truck with 90,000 miles has been doing it for a long time.

He did show me that depressing the break after shutting off the engine will prevent to noise. The noise is happened because air is equalizing but if you depress the brake after engine shutdown you are breaking the vacuum. I've tried it multiple times today and he is correct, it does stop the sound.

I tried to find a copy of TSB 13-10-7 online but couldn't find it anywhere. If you want a copy I can e-mail it to you, unless someone can find an online link.

 

Just thought I'd update this thread.

Truck now has 81k on the clock and the noise is still gone. The replacement waste gate solenoid is still performing without any complaints. (Too bad that was not the ONLY issue that I've had with this thing)

Another happy customer here. I have a 2012 6.7 F350 dually and it started buzzing after shutdown, then started doing it all the time. I replace the solenoid and it's gone.

 

the noise after engine shut down is the vacuum pump drawing down the res tank , it is running all the time the engine is running because of a vacuum leak . you don't hear it over the sound of the engine running . you need to fix your vacuum leak and it will stop,

 

I'm getting nervous now, my truck has been making this noise since it was new and I didn't think it was an issue. I'm getting it looked into this week, I don't need any turbo issues arising from failure to act on a known TSB.

 

Update from the previous thread. Dealer confirmed my waste gate solenoid was bad. Parts are on order and the work is being performed under the Diesel Powertrain warranty. The mechanic said he didn't think it would cause any damage but eventually could go into limp mode when the solenoid fails.

 

Anyone have text for the TSB? What part number is the wastegate solenoid? I've searched but can't find anything other than the actuator that is on the turbo.

Mine has always buzzed for 30-60 seconds after shutdown.

 

From my invoice from the dealer the part number is BC3Z*9D430*E Connector - Vacuum Hose.
