Cummins shut off Clicking

[Danishgod]

Members, what is the clicking that happens when you turn off your cummins? There are three distinct clicks and then it stops. I assume it is normal but i see nothing on this matter.

DEF system and EGR cycling I believe, totally normal.

Pretty sure I saw in the manual somewhere that it was purging DEF lines.

Frequent question here too.

Should add a sticky but there are already so many and nobody uses search anyway.
