Darn I want to love this engine but now have second CEL. Code P00AF came up with directions to a possible Turbo Charger issue. Anyone else have this problem?

You stock engine or any mods?

P00AF I've seen caused by a leak post-turbo that leads to the PCM not seeing the boost it expects and throwing the code you mention.

Engine is stock, have added some accessories, winch, on board air compressor, and a couple of lights, but nothing to the engine. I did have first oil change about 1k miles ago. Understand there may be some engine air intake parts required to be temporarily removed to get to oil filter, but dont have a clue of what the dealer actually did. Going into dealer for a more precise and official diagnostic test today. Will post results.

On the Wrangler application, the airbox is (stupidly) placed on the driver side, directly covering up all access to the oil filter. The ductwork going from the airbox to the turbo was likely removed to do the oil change. It's possible they didn't tighten some of the clamps when they reinstalled. I'd check that first.

Update: Just heard back from the dealer and this is MAJOR problem. Not only is the repair job extensive, it's a parts problem too. I may need to give the parts department a thumbs up effort for finding all the parts through various means as opposed to the complete Turbo Charger assembly. Best estimate is that they will need two weeks to complete this repair. One thing to note is the repair requires them to "pull the cabin" which has us worried that they have the expertise to get this job completed without issues. My wife and I have come to the conclusion that maybe we made a mistake in going the diesel route. One more CEL and it's Adios to Rubi 2.

It could also be something simple and the dealership is milking FCA for money...

This makes no sense at all. There is nothing that could have gone wrong that would require to "pull the cabin."

Ever pull a turbo out of the valley on a V engine? The engine bay looks awfully cramped on these 3.0L Wranglers.

I'm not saying they are right and the whole tub will have to come off, but I could see that being the case.

The shop manual for the JLUD says the turbos can be replaced in the vehicle (6 hours). Looking at the engine bay it doesn't look like anything is restricted to prevent access to the entire valley area (once you remove a bunch of stuff). On some BMW's and Audi's it gets difficult as the engine is back under the cowl and windshield base. But the Jeep doesn't have such an overhang.

If they need to pull the tub this would be a serious reason to not purchase a JLUD as it means post-warranty repairs will be even more insane $$$$$.

One more reason NOT to get a 3.0...

She goes in Tuesday for an estimated 3 day repair job. Won't get back until the end of the week. I'm going to make sure the service manager tells me exactly what failed after they get it apart. I wish I had an exploded parts list so I could understand how this turbo charger works and where the likely points of failure may be.
