Engine went noisy on me

[PHXDiesel]

I was driving home from work one day, and decided to run through the starbucks drive through. I thought the engine sounded louder, and when I had to struggle to place my order it was confirmed. It was about as loud as my old 6.4l, but still sounded like the 6.7. I waited in the drive through line for a couple minutes and decided to throw it in neutral. After about a minute in neutral it went back to normal. I'm pretty sure it wasn't in re-gen mode... I watch the instant mileage screen constantly and didn't notice anything out of the ordinary. I also don't notice the engine being louder during a regen (I paid close attention during the next regen).

Has anyone else had this happen?

Hasn't happened to me.... but Real trucks don't go to Starbucks.
Maybe it was upset because all of the Chevrolets made it feel uncomfortable.

Just kidding.

How many miles do you have? Have you had your first oil change yet? Did you just get fuel? Maybe bad diesel? Was it cold outside?
Please keep us updated.

Haha, I didn't think it would take long before someone harassed me for starbucks. I love the place, but it gives you way too much time to sit and listen to your engine and all the noises it makes with the reflective walls on both sides. Maybe I'm just so strung out on caffeine I'm imagining things .

I'm sitting at about 2200 right now. Still on original oil, didn't get fuel recently. I did regen later that same afternoon which is when I checked to see if it was as noisy at idle(it wasn't). It wasn't cold... I'm in the phoenix, AZ area and at the time it was in the 90's as this happened a couple weeks ago. Truck was at full operating temps.

Luckily it hasn't seemed to cause any issue at all. I just found it a little strange. There have been other times when I thought it was louder than normal but they have always been before the engine has reached full operating temps.

Anyhow just thought I'd bring it up.
