definately will be on the other side of the egr. get a long hex bit and a small socket or spanner to get the final bottom bolt out. fiddly but its doable.
Is it true that cutting out the EGR makes the car harder to start and lumpier and tickover?
Not that I've noticed.
But I'd rather have a little lumpiness than an inlet manifold full of shite.
Hence my CCV bypass too.
See more of my war on the black gunge here
you can just see the little golf tee

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?

What I meant is how did you go about getting those results from VAG-COM? Log block 003?
Anyhow, I've been out with my laptop and figured out how you did it, I shall post my results soon.
Engine speed 790-870 = 903
MAF Specified mg/R = 335
MAF Actual mg/R = Varied between 392.0 and 411.6
EGR Duty Cycle = 84.5%
This is with my EGR vacume hose blocked. Not sure if any of these results are relevant though, i'm doing some reading on the EGR's on TDIClub.

VAG COM
Engine Module

Group 003
It will increase revs to 1400RPM, start logging.
This is what I got; don't understand why the EGR duty cycles between 64.5 and 19.9???

182.81 1407 EGR On 485.1 64.5Infact reading those results again shows my EGR turning on and off. I suppose doing these logs with the EGR vacume blocked won't give me proper results.
Very good question, from what I have read tonight some bloke is saying the PD EGR system works on electrical sensors/solenoid system and not using a vacume system.
But I don't see any wires going to the EGR so this may be complete twoddle.
I would be interested to see you log block 003 via the 'basic function' button.
I'm going to read into this, but my head is too knackered to understand anything tonight. Maybe someone on here may read this and give us a understandable explanation.
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.

I shall find the link when at home tonight, can't seem to find it now. I have it bookmarked thankfuly.
Yep correct, the ASV connector is behind the big silver cap for the EGR, look behind and down a little, theres a connector there which attached to a clip on the side of the egr valve.
I run an allard EGR replacement I get shudder on turn off (almost un-noticabe though) and the emission light comes on sometimes. When measured at MOT my emission have actually gone down.
I had a performance gain of 5BHp according to dyno. Plus I gained on average 2mpg on a long run. My EGR valve was a mess almost half the diameter was clogged full of crap.
