Trouble finding a part for my truck

Last week got a check engine light. Pulled the codes out the keeptruckin app and see 3 codes all having to do with the Particulate Matter Sensor (part# 68352149AB). I have searched all over the web and called 6 or 7 dealers and no one has it in stock and they can't find any dealer across the country that has one either.

Any tips on where or how to get the sensor?
I'm still running the truck, hope I am not causing any extra damage to the DEF system by doing so.

Not only that but came to the truck at the start of last week and a tiny chip in the glass that has been there for almost 2 years turned into a crack that went across the windshield side to side $625 oem windshield installed. Would have been half the price if I didn't have all my fancy tech sensors on the mirror.

 

I have automated high beams, active collision mitigation (saved my butt once), rain sensors and adaptive cruise control.

On the keeptruckin dashboard go to "Reports" tab and look for "Fault codes".

 

Had my dispatcher talk to her. Been over a week, still waiting on answers from her...

 

Here are the codes I got:

 

All the insurance brokers just keep going to Progressive for quotes. I need to find an insurance broker that works with other insurance companies. What's funny is that every broker gets the exact same information, gets a quote with progressive and comes back with a different price... Frustrating.
