2024 High Country 2500HD DPF Restriction Code

[That1Silverado]

Hello everyone, I just picked up a 2024 High Country 2500HD Duramax on Monday, and last night as I was backing into a parking spot at a restaurant I had noticed the check engine light was on (Truck had just got to 300 miles as I pulled into the restaurant)  Luckily I have my small little scan tool with me, and it read the code P2463 - DPF Restriction - Soot.  Truck had no messages or anything come up on the DIC, only the check engine light.  I cleared the code and drove home (about 35-40 miles) and it never came back on.

 

My main concern is, why would the DPF already be clogged with only 300 miles on the truck?  From most people, I have read the truck does regens at about 800+ miles.  Any input would be greatly appreciated!

I would think it somewhat depends on how it was driven.  I could have idled for days for example.  In my experience, the Regens happen at about 800 kms or so (500 miles).  This was the case on both my '21 and '22.  My '24 just had its first one at 725 km or so.

probably a sensor fluke or problem
