I have an 2006. I was at my dealership last week and got the turbo cleaned as it was all sooted up and the unison ring was not moving properly. Luckily they cover it under warranty since it is part of the emissions control system extended warranty. They referred to something called "Cleaning per TSB". Does anyone have access to the info in this TSB? It would be nice to know what is being referred to for down the road when the truck is out of warranty.
The dealership also recommended using a cetane additive they sell to help reduce sooting - for a steal at over $10 per bottle!!
