Question about tier 4

[Sysop]

IF epa paid for it and all the costs that goes along with it when there is trouble then sure haha im sure that would never happen

They don't pay for it. They actually mandate that the manufacturer's must pay for emissions related repairs for X amount of years, well beyond the regular warranty. That is part of the massive increase in cost we see every time new standards are required. Customers are paying an extra built in "just in case we (the manufacturer) have to replace emissions stuff 7 years from now" fee.

What is this Regen all about?

 

[Sysop]

In simplest terms; the particulate filter requires cleaning which the engine manages itself. "Regen" (short for regeneration) is the cycle of cleaning itself.

No, I don't think so. I don't know the LS models that well, but if it was manufactured in 2012 it is likely an interim tier VI, not final tier VI and won't have a Regen.
