Never ceases to amaze me the problems I encounter with this damn truck.
After a slew of warranty issues that would shelve the Super duty series, the death wobble which I had to cure with a dual stabilizer which does not fit, after a few mods, fits now. But what the hell, its working, Now, I have these 3 fricking codes that popped up, guess this happens when you hit 60k in miles. The codes are: P02043- reductant temp sensor circuit thingy, U0073-control module com bus A off, P0500-Vehicle speed sensor. What's even stranger, when I go to turn the truck off after driving, etc. the motor will begin making these noises like a vacuum type sound Brrrrrrrrrrrr, on top of the motor near the turbo. Of course, the dealership will rape me in diag fees and labor, probably these components are impossible to get too just short of a chassis cab lift. Are these failures feasible to get too and can I do them myself, I do a lot with wrenches on my truck, Id rather know I can attempt to fix these and just pay for the parts. Pls, anyone out there can help me, before I screw myself by relenting to the dealership path? One more note, I do have the ultimate Diesel care warranty they gave me in hopes of just go away pls customer, but Im not sure if this would be cvrd under that.

I know on the semis with DEF there is a pump that sucks out the lines. This is so that if it freezes the lines don't break, and are not plugged. That may be your whirring noise.

Any time you get multiple codes at once. you want to clean the battery connections and the grounds. You want to start at the basics.
Just a thought!

Your warranty will cover those codes. Take it in and let them deal with it.

The buzzing noise I get when at at idle and after shutdown is what people are calling the wastegate solenoid, but as long as it doesn't cause performance issues it doesn't bother me too much.
After shutdown:

While running:

I got this printout from the dealer noting the part in question.
