So it might be crudded up further down the pipe? I need to shrink my hands.

591 miles since egr vaccuum disconnected
NO CEL LIGHT
OK I took a log today using VAG COM of what the EGR is doing at idle.
I have done the thing that turns it down using VAG COM and have also plugged the top vacuum pipe going into the EGR saucer with a golf tee so it is disconnected from the EGR.
This is what I logged with the engine at idle
Engine speed 790-870 = 903
MAF Specified mg/R = 350
MAF Actual mg/R = Varied between 411.6 and 441
EGR Duty Cycle = 84.5%
Can someone please interperet these for me as I am no mechanic, but from what I gather it means that the EGR has been successfully disabled?
I used VAG COM.
Are they bad?

So is our EGR blocking actually working then?
Or is the EGR still functioning?
wheres the link for this chris?
With the EGR vacuum hose disconnected and blanked off the EGR valve will stay closed. So it's not actually working.
However, you're using Vag Com to read the ecu which is still ordering the EGR to operate as required and that's the readings you're getting in Vag Com logs. The ECU is still telling the EGR system what to do but the system doesn't operate.
There's an electrical connection to the 2.0ltr EGR valve assembly but it's purely for the anti shudder valve system (closes the flap valve on shut down to stop engine shudder), possibly the same on the 1.9 aswell.
