guys I wanted your opinion, I have the egr valve of my 1.3 mjet 90 hp closed electronically, then in theory it should work, or allow the passage of any thing, some friends told me that even if ? closed electronically in a bit always remains open, and then you can? clog up as if it were enabled, tales, or do you ? a shred of truth?? I opened this topic because? I would like to tapparla with a flange permanently in aluminum of the size of the gasket, but if you already? with the electronic lock and the same thing that the tappassi, then I leave everything as it is. thanks

You have said this, why? from the diagnosis to see 3-4% but really? ? closed.
The council ? always the one to clean it well and then close it electronically, and you will not have problems.
If you want to clamp anyone you forbid this, but ? a pi?.

yes, if ? clean and close properly, even if some times it gives you a small percentage in the diagnosis, no matter ,anyway, as you said alpha, you can always tapparla.

how to tell the colleagues when it is plugged eletronicamente not open+, however, may leak a little if there is no' perfect tightness to be sure 100 percent sometimes I siggillata I also with the sheet

so instead, if you stop only with the lamella and not in the ecu what problems there would be, considering that many of the close with the slat without remap. no light on say.

it depends on what type of egr valve and mounted on the motor.. there are various types of egr valves.. pneumatic, direct control with 5 wires on the plug where there is a potentiometer that informs the ecu on the actual percentage of opening of the valve and the last type, and indirect control with 2 wires on the plug that controls the percentage of the opening through the quantity of air that passes through the mass meter air on the latter will not be possible to close mechanically with flange

my reference was about 1.3 mtj thanks.

on some engines, plug with a sheet, the egr valve port some changes to the pressure of the turbo. If you have made some certain processing are things to keep in mind.

For example:

1.9 jtd engine . If you put the plate right at the exit of the manifold(the cio? the intake side), decrease the volume of the manifold and not just a little (see, for example, in the 105cv eliminate all of the metal tube). The result: obviously decrease the turbolag but you'll have a peak pressure pi? the top, just those peaks very harmful for the turbo.

They are expensive, but in some cases, make the difference

then I 83000 km I'm never open it polished the egr, 72000km when ? made the map and was only excluded electronically, and then you say I remove, clean, and to go and secure the cap with a strip?

I think you are right GIA. and then leaving a little I think it will go better,

then with the plate to increase the pressure of the turbo? or it happens on some cars? why? if ? so putting the sheet, you should retouch the map

Parts from the assumption that the egr at high rpm tends to stay closed.
However, closing it electronically or with sheet does not change anything if it closes well do a job in ir?.
If you take out all the pipe of the circulation, then ? another speech, but even in that case, not c'? you need do nothing. I never lowered the prex turbo for this intervention.

ATTENTION! do not increase the turbo pressure, but the pressure peak.
Fit a pressure gauge and make the case to the trend of the pressure when you sink the accelerator. the pressure, for example, tap for a moment, 1.1 bar, and then stabilizes to 1 bar. 1.1 and the pressure peak, plugging the egr in the way that I said I,you may have peaks higher, especially if the machine and mapped. Not all machines are equal, we need to see the structure of the ducts of the egr itself.

ah now I understand the whole, increases the peak, vabb? I try to clean it cos? a day after if I had to return the car original, I find myself already? with the egr clean, seen that ? closed electronically, I'm not going why? ? needless to put the flange, thanks to all for the info

I have tried to exclude it electronically mettendoo a resistance 33hom or 39. THE result? just set in motion, no light, the machine was fine, but then the second hang-up, puff, light on.
