Help egr valve

iam new to this

but can any one tell me when the egr valve should open at what rpm,

and should it close at the same rpm instantly

as i have run a diagnostic on my 08 147 sport q2 jtdm 16v

and it starts at 4% up to 2000rpm then increases but dose not drop down to 4% when the rpm drops below 2000rpm for a approximately 45 sec,to 1,min then returns to the 4%

is this normal or is their a potentially a problem

EGR is there to circulate exhaust gas back through engine on over-run, i.e. when you lift off throttle whilst in gear, which as I understand it helps maintain cylinder temperatures, thus improving fuel burn when you put your foot back on throttle, improving economy / emissions. As such, it won't do much sat still on your drive! FiatECUScan has a facility to test the actuator, other than that you'd have to take it for a drive with the pc attached.

When mine was sticking an causing a power loss, I found I could avoid this by never quite lifting off the throttle when slowing down - OK as a very short term drive-around...
