hi , yes i'v done it on a 320d N47 engine and unfortunately i didnt take pictures, anyways here is a pic of what you have to close down that's all

Uploaded with ImageShack.us

after doing so i got no fault codes on my odb just i can hear something like the turbo but it's not the turbo and that only when the windows are closed.i dont know if you can pass the controle test with this on or not ,fortunately here in morocco i can still pass it . enjoy

Will this increase power then seeing as the engine will be cleaner?

this will not increase the engine power, but ur engine will breathe much easier and sound much better, and likly to go a bitt better due the clean cold air against the hot air from the exhaust.

Normally an EGR delete doesnīt do much for power, but it might give you abit better fuelconsumption since your not burning spend exhaustgases but only clean air.

The problem is that most modern EGRīs have a "cut out" that stops exhaustgas from entering the intake when you have full throttle to increase power. On older gasoline engines this easy to control, since it was vacuum controlled. Low pressure inside the intake increased the spent gas use (EG. coasting would burrn more exhaust gases).

The pros are better fuel milage and maybe midrange torque.
The cons: Illegal to mess with this stuff in most countries. Your car will fail inspection if they do an exhaust gas check. No "real" cons on the mechanical side.

I did a EGR delete on my old E46 -02 320d and drove it for 100.000Kīs with no issue. Same setup as this. Iīm thinking about it on my e91, i just want the new car garantee to run out before i mess with anything.

hi,
i have one 320 ED 6mt N47N (2010/10)
i sealed the pipe(part 21) nearby the inlet manifold,
but it shows the engine error signal,
I guess that error is caused by the temperature sensor on the part 21,
but i can't sure.
it means i can not seal it or just wrong position?
N47 320D has the temperature sensor nearby the manifold?
i check the EGR(AGR) figure between both two cars, it's different
i have no idea of it, thanks for your help ^^
