Field Service 17M04 - Crankcase Ventilation Oil Separator Assembly

Anyone know what this is for?
17M04

I guess my truck send a report and this is what was emailed to me.

It's a FSA/TSB with extended coverage 11 year or 120,000 miles for replacement of the oil separator if there are certain dtcs for the ccv system

So don't worry about then?
Mine has never thrown a code, its not seeping and hoses looked good to me.

They are real common for the sensor to fail, so the warranty was extended, kinda like the egt sensors.
