Need some input

I bought a used 2011 GMC Denali HD, with 5600 miles on it when I took ownership. The check engine light came on about a month ago, so I took it to a GMC dealer. They replaced a sensor that tells what position the vanes are in on the turbo. I drove to Michigan and back, about 1500 miles. Half way back, check engine light came on again. Went to the dealer again today, now they say it is throwing a code that indicates turbo is carbon-ed up. I was informed that they will clean the turbo this one time, and if anymore turbo problems come up, it will be on my pocket book. Dealer said it takes two days to do the job, because they have to take the cab off the truck. I just feel like I am being played here. I was thinking of putting some "Sea-foam" in the tank, but not sure I should.

Has any of you out there ever heard of such a thing?

I do know that accessing the diesel engine components on the vans equipped with the Duramax was a huge issue and some work required body removal. This proved to be such a problem that the B.C. Ambulance service is switching away from the diesel powered chassis they had used for 4 years , because after the ambulance body was added , engine work was next to impossible.
Extreme low mileage diesel, sounds like the original owner bought a diesel for all the wrong reasons, the way he ran the vehicle probably contributed to the carbon build-up.

Vehicle comes with a 100k/5 year warranty. Dealer is wrong...never heard of a code for carbon.. btw it only takes a few hrs to remove the turbo even with the cab on. I have cleaned mine also while I replaced the VGT vane sensor (went inop) that part can replaced in 1 hr. But my vanes would not schedule back and fourth at idle hence the removal ...btw seafoam will do nothing for the turbo but will quite the injectors down, I use 2 cycle in the tank or b20 to quite mine
