when in regen the engine can sound louder and a little more tick sound, also my LLY and LMM both had tick on drivers side wheel well when idling, was normal sounds for this diesel engine. Does the dealer think that it is also an unusually loud or different noise?

No problem. You're not the only one who has expressed concern over the infamous tick. I've posted that link probably 100 times.

2011 Chevy Silverado HD3500 - Duramax

The truck is one year old. I just did the second oil change because I was going on a cross-country trip. While picking up my camper, I hear the infamous ticking noise. One year ago, I had the water pump replaced due to a service bulletin. I thought it was the water pump starting to fail again. Quickly took it top the Chevy dealer to diagnose. Want to see what they say. I see Service Bulletin: 02-06-01-022K. Yeah, not real happy.

What are you worried about, can cause no harm, nature of the beast, never had any Dmax that didn't sound this way, nor have any problem resulting.
