Hi & welcome aboard.

I think you might get more help form the 407 forum or facebook group, as their experience will be more relevant than ours.

I have a 2009 C5 2.0 HDi but am unable to communicate with the engine ecu unless I use settings for a 407. The information available by this method is very limited.

My brother had a 2007 407 2.2 HDi with possibly similar problems which seemed to indicate a failure of the air doser. (If I remember correctly this device also measures the air flow). The common mode of failure for these is wear to the pinion / gear that drives the throttle flap.

In his case, cleaning and unplugging / re-plugging the air doser electrical connector several times improved the situation at least temporarily.
