its fine for PDs as far as im aware, its just that some wont let you do it, as I mentioned in the TDI FAQ on here in the TDI section.
I'm going for the ultimate EGR disabling very soon. I have named it the "get the f***er out my engine bay" technique. Getting a straight pipe put in mine, with another samco type bend to finish it off.
Just wondering though - I'm sure there's a trick out there for the EGR vacuum hose so it doesn't throw a fault with the EGR, bringing up the CEL light. I need to do some experimenting. I heard blocking the pipe off, then drilling a tiny hole through the blockage would work well.

slow down devon,,,
in the EGR assemly there is said valve AND the anti-shudder valve.
The antishudder is basically an air choke system that is used on engine turnoff. When I was changing the vac hoses on my car, I managed to break the nipple at the end of the black mushroom thing which is near the EGR. That is the anti-shudder valve actuator [also controlled by the N18]. On every engine turn off I got the car shaking like los angeles during earthquakes,,, not that good for the engine mounts,,,
Now, I've heard some don't have this prob and on dieselgeek they sell the so cal racepipe which is a straight pipe instead of the EGR [so basically the thing from you took the idea off
] so it must work on some tdi's,,, but I don't know on which,,, on mine it deffo didn't!!
If I was you I'd [carefully] disconnect the vac pipe at the end of the antishudder actuator and see what it is like on engine turn off,,, lemme know then,,,

Well - a bit of shaking I don't mind. It already shudders a little bit on shut down and the boost guage does its down to -0.6 bar blip.
I shall see what happens - I know of one other Fabia with one, and a Golf pd130, so fingers crossed.

it wasn't exactly a bit lemme tell ya,,,
and maybe your engine mounts will mind about it
try what I've said: disconnect the antishudder valve hose and see how it goes,,,

I thought the fault occurred because the MAF was seeing more fresh air being taken in than it expected (because the ECU expects a certain percentage of the total intake to be exhaust gas through the EGR valve instead).
Could be wrong though !

Afraid I think so.
The fault I get is something like "EGR: Maximum range exceeded" - which means its after a certain amount of air/recirc to monitor, but its getting sweet F.A. ![[B)]](/forums/styles/seatcupra/oldforumsmileys/shades.gif "Cool [B)]")
Hoping that with a small gap for air to still get through the pipe into the vacuum box, it will be faked into thinking the EGR is actually working. nothing MAF related at all.
try without the hole first, I've been running nearly three years without a fault, Bosch EDC? 15 is your's a newer typedevonutopia said:Afraid I think so.

EDC? You mean the ECU? Its one from a 2004 vRS.
At the moment its effectively sealed off as the EGR unit is blanked off. and my CEL comes on and stays on.

yes ECU, Bosch EDC15, is what most of us have I think, I thought EDC16 was US only but I am not that up to speed on this, do you have the over complex EGR valve like the Yanks? if so I guess you may have a problem or live with the light as I don't think they have a fix yet.

I just have the usual PD130 EGR. I've seen one other photo of a Fabia one removed, and I know Micky's is no longer on his golf. So it can't be too tricky. Its wondering what to do with the vacuum pipes.
Thanks for the ECU clarification. Its a UK standard fabia vRS ECU, thats all I really know. (apart from the fact its chipped)

keep the anti shudder on and blank the EGR diaphram pipe, assuming you're going to keep the valve on, if removing all together, cut the antishudder pipe to save the valve or it will break the nipple if you try to pull it off, won't it Carlo???
OK - I'm muchos confused now. Where exactly is this anti-shudder thing? Looking on my parts catalogue I have something called a "damper" on the front of the engine, with a round ball on top of it, and a vacuum pipe coming off it. I hope this drawed on pic makes sense?
the thing you have marked as antishudder is in the real thing the vacuum expansion box.
the antishudder is a sort of choke valve INSIDE the egr assembly. Where you've written 'remove'.
in this pic you can see the EGR assembly modified [by nic] to avoid egr function. the horizontal line in between is the antishudder valve,,, on engine shut down, it rotates on the horizontal axis and closes the whole air duct to the engine, in order to 'suffocate' it,,,
it is operated by the black thing you see at front right of the image [the black mushroom thing as I call it]. That has a vacuum diaphragm in it that, if the air is sucked, pulls the arm that goes to the antishudder valve axis, making it rotate and close. The mushroom thing is operated byb the N18 valve [or the black vacuum box on newer engines].
hope this helps,,,

oh, btw, to balnk the egr I'd fabricate a metal piece with the exact shape of part #4 of your pic [that little gasket that goes on the flange], but with the center part filled,,,
