16785 - EGR System: Insufficient Flow

[chrisgeary]

Hello,

I have a 3.0 Tdi reporting:

16785 - EGR System: Insufficient Flow
P0401 - 002 - Lower Limit Exceeded
Freeze Frame:
RPM: 2037 /min
Torque: 187.2 Nm
Speed: 114.2 km/h
Duty Cycle: 51.8 %
Duty Cycle: 20.9 %
Mass Air / Rev.: 581.6 mg/str
Duty Cycle: 58.4 %
Mass Air / Rev.: 405.4 mg/str

I cleared this yesterday and it came back today. Not sure if the car is down on power or not, it feels pretty ok to me.

What might be the cause?

Might be the valve, but check the hoses to and from the valve - for any sign of splits.

Have you lost power?

I don't think it is down on power. Feels good, nominal levels of soot from the rear under full throttle, I'll check the hoses, no other engine fault codes that I might expect with a split hose. I guess if it isn't bring up an alarm on the dash and there isn't a power loss, perhaps I should just ignore it?

Might be worth taking valve off and cleaning out. it is an easy job. My daughters was vitually blocked when i checked it
