This is pretty typical for me on flat ground no trailer and no major headwind at 76mph

Here's a unique back to back test with smaller tires. One of my 37" tires failed on a trip and in an emergency I got 32" tires today to get me where I'm going.

Not a huge difference for EGT but it does show the tire size impact on engine load. This was while traveling 76mph on flat road with the necessary corrections for tire size.

Do you have your Jeep programmed for the 37” tires? If you have a tazer, it’s pretty easy to do, and will get your shift points back closer to like they would be when stock.

My EGT 1/1 usually run 800-900 on flat ground not towing on the highway, but it will get up or slightly over 1000 when pulling a decent hill.

Yeah I always correct for tire size and verify with GPS.

Hi @DC3 I'm close to having an appointment with the dealer to pull the cab and swap my turbo to address the P00AF issue and just found this thread. I would certainly rather pay out-of-pocket to replace the turbo actuator myself than go through a cab-off with the dealer to replace the entire turbo.

Now that you've had the new actuator in use throughout the summer, do you have any update on whether this fixed your issue?

Your Polish rebuilder is currently out of stock on this actuator. If this is the fix I need for my Jeep, then I'll be anxiously keeping an eye on his listing!

The new actuator significantly reduced the P00AF occurrences by a factor of 10. Ultimately, the turbo failed and I am currently getting the turbo replaced. I doubt the actuator had anything to do with the failure but I noticed an increase in POOAF occurrences in the last ~1,500 miles leading up the the failure. Photo below.

If your dealer is willing and able to swap the turbo, I would do that. Sure, it comes with risks but the alternative actuator swap is a band aid fix in my humble opinion.

Photos of the failed turbo from my borescope are included below.

Jeez, you've had quite a bad stroke of luck with your turbo. Keep us updated on the repairs. Thanks a lot for all your information and advice.

what did the turbo eat?

As for the turbo failures what was the condition of the air filter at the time of failure? Filter recommended to be changed at 30,000 miles so how many miles on the filter when the turbo went?

My engine has been replaced, they used a full crate engine which included a new turbo. I don't have the root cause details for the turbo but I do know it didn't ingest a foreign object. I had an AFE cone filter that had been cleaned a few times within 25k miles.

The dealer tacked on $5,500 in labor for aftermarket part inconveniences like my solar panel wiring, rear cap, air suspension, bypass oil filter & cooler, aftermarket EGR cooler swap, etc.

They had the Gladiator for just over 7 weeks and it took just a couple of weeks to get the engine. All in all, I am happy with the results. No other dealer would look into the issues I've faced for 40k miles like coolant consumption,P00AF, snap overheating,etc.

I have 100 miles on the new engine and will share my experiences through daily driving and towing.

A few snapshots of the ticket are included below.

what does the rear cap or air suspension have to do with an engine replacement?

Also, what air suspension and how do you like it? I've been contemplating the rear only kit from Accuair, even though they don't offer it for the diesel (unsure why, guessing DEF tank is in the way of the compressor from the looks of the install instructions).

I have the Accuair system which has several wires running into the cab for level sensors, controls, etc. The wiring running along the frame/body and evidently the cap prevented the body from being lifted without adjusting the cap. I am sure most techs are accustomed to working from an explicit set of instructions. Venturing into the unknown is a significant departure.

I like the Accuair system, it allows me to park in parking garages and drive through low height areas. It's a decent ride too. They place the compressor where the spare tire would be.

Interesting finding on the actuator part numbers:
Original Actuator:
Part: 6NW010099-24
Firmware Revision or calibration: 797862-0050

New Turbo Actuator
Part: 6NW0010099-24
Firmware Revision or calibration: 797862-0072

In talking with the Polish eBay repair guy Peter, he shared the following information with me:

797862-0050 - is 6NW010099-24
797862-0072 - is 6NW010430-43

I haven't been able to find one available without also purchasing the entire turbo assembly, so I am awaiting him sourcing one for me.

The one I purchased from him does not have actuator location feedback. You might raise that to ith him to ensure you don't receive something that causes more problems.
