2017 2.0 Adblue hunting on first start up

[ultracoach]

Hi, on initial start up in the morning , it hunts for a few seconds , then settles down to normal and no further issue. Is this a sign that a regen is required , or something else..? Many thanks

You are not alone, has it developed further?... Or have you found/diagnosed the issue?

I am looking for possible causes for the same symptoms with my 2016 2.0 Eco blue.
I'm thinking a micro air-leak in the fuel system somewhere.. it fits the profile.
