Hi all,

I done a diagnostics test on a mates car for him as he had the emissions warning light on his dash illuminated.

The test flagged this up:


16785 - EGR System: Insufficient Flow
P0401 - 000 - -
Freeze Frame:
RPM: 1680 /min
Torque: 78.0 Nm
Speed: 54.0 km/h
Load: 21.6 %
Duty Cycle: 14.7 %
Mass Air / Rev.: 280.0 mg/str
Mass Air / Rev.: 525.0 mg/str


What does this mean? New EGR Valve?

Can anyone share some info if its happened to them before? Or how much a new part will be?

Cheers, Greg.
