1.9 tdi egr insufficient flow

[meakylad]

Just wondering if anybody could give and advice, I had a management light on and it was the above fault so I replaced the egr but to no avail? Could it be the motor part? Vacuum lines look ok too

Cheers

Air mass monitors egr quantity so if everything's to spec with the egr itself this is the air mass reporting implausibility during egr function. If you have a decent scan tool, actuate egr at idle and monitor egr vs air mass. Air mass should drop as egr is introduced and vice versa.
