Build was 05/10

Wondering if aging of the part has something to do with root cause. We all need more information on this part failure.

Ah, another May build. Mine was 05/15/10.
I've been fairly happy with the May build except for the transmission but that is more widespread than just a few bad small parts.

 

For the curious out there:

Wastegate control solenoid:

Located top front left side under coolant hose & compressor outlet hose.

I was listening to mine right after a short idle run to check the Tx Fluid

It kind of sounded like a solonoid relay that was buzzing along for about 10 seconds or so. As soon as the EGR Cooler Bypass Actuator closed (located on top of the the EGR cooler) the noise went away. I actually watched the valve release after the short duration.

You may want to run her up with the hood open for a few minutes, then shut it down and watch what is going on.
The sound you recorded seemed similar only louder.

 

My 'abnormal' noise happens immediately after the EGR Actuator cycles.

I do hear some other, what I call 'normal' noises prior to the EGR Actuator event. From listening to other 2011's, that seems like the run of the mill.

If you think you may have the same issue, I suggest you schedule an appointment with your service department and have it checked out.

Update Friday May 13:

Fixed!


Kudos to the boys at MedVed! Got me in and tech replaced the solenoid while I waited.


Gary, the service writer I worked with, told me the new part had (apparently) a first series part number.


Gary also advised me to keep my eye on the problem to see if it returns.

The truck is back to being its old quiet self again! Color me satisfied!

LOL, you got the 1st one !!!

 

Interesting, we just bought a 2011 with 30k miles and it makes this noise for a good minute or so after shutoff. We are all standing around wondering is that normal? Good to know it's not, will have it checked out.

 

The 2012 Freightliner Cascadia trucks (Detroit DDC13 engine) we have where I work also make funky noises like my F350, after shutdown.. must be something to do with the emissions stuff?
I just wish Ford would've put in a DEF level gauge like the freightliners have..

 

LOL or a hoodoscopy.

I almost sounds like the trimmers at the barber shop, glad to hear you got it resolved.

 

LOL good timing. My truck just started doing this last week. Does anyone know if there is actually a problem, other than the noise? It really doesn't bother me and I am not all that excited about taking it into my dealer. If the noise is the only issue, I will leave it alone.

Thanks

 

Personally, I would definitely have it fixed.

The noise indicates some sort of vacuum failure within the part. When I was trying to locate the offending part, I discovered that if I bleed the vacuum by pulling one of the hoses, the noise stopped immediately. I could also kill the noise by hitting the brake pedal a couple of times (also affects the vacuum system).

OK, thanks, so it was the wastegate control solenoid they replace then right??

Wonder how many trips to the dealer this will take

 

yep, wastegate solonoid was replaced.

Thanks Jammer, you don't happen to have the part number do you?
Easier for me to just buy one and do it myself.
