It would appear that many of those who have been remapped have had their EGR valves disabled, mine is, but it would be nice to have an explanation from the likes of BAS (who appear to do lots of remaps) why this is the case and if it is likely to cause any problems in the future?
As usual there are varying opinions abounding on the forum some will be more knowledgeable than others so it would be of benefit to hear from an expert.
I don't doubt that some of the posts regarding this thread 'are' from knowledgeable sources so no offence is meant to those in the know......I'm not one of those people.

So what is the best bet?

Take the gears out and sandwich a blanking plate on the egr intake?

Or

Turn it off?

The gasses in EGR are actually corrosive to the engine!

Better MPG?

I would say you need to leave the gear in that reads the postion of the valve otherwise the mil light will come on

but maybe take gear out that drives the spindle , making sure the valve cant open and stay open

you may find that the mil light will come on after a while as the air reading from maf sensor will not be as programmed in to ecu without the egr opening and closing as it should

sometimes the mil light will take a good few miles to pick up a problem

only guess work as never done it and it would be up to you how you do it !!!

I just reload the standard map every few months to let it clean itself for a few days. The EGR has to continue to function anyway or it will fail the TÜV

how would they know for the tuv thing if its not working

I removed my EGR valve, open it up on top, removed the two drive gears, close up and install back. so the drive motor still get power but no gears to open up valve. The valve open up on a spring, so when power is cut the valve close. I also cut the small pipe to intake and weld both ends. I done now 4000km without any warning lights, this is now 4 weeks on running without EGR valve.

Since my egr was playing games and eventually pulled the plug,i'll try the same!!

Didn't work for my 2.4,too good to be true

PS
I know I already posted it elsewhere,sorry..

I think I have the same sound and problem as you, Dieselhead
.
It comes irregularly. And only at low speed or when I go from running to idle.
I'm not 100% sure that it is EGR.
I have tuned the car and removed the EGR funktion with remap.

You find a solution?

For those without a remap I only know of one 100% proven method of reducing not stopping the pollution. I ran with this method for about four-five years with a different map until the EGR disable function became available.....

You started at the blank with the largest hole and ran with it for a week or two and gradually reduced until you got a MIL light and then went back to the previous blank that didn't illuminate the MIL light and left it at that. Each vehicle being different with air filter, RAI/Snorkel etc. different set ups ended up with invariably a different size orifice blank to keep the MIL light off. Even running with a blank for just a couple of weeks it was amazing how sooted up it became. No clean cycle on my map currently.

If you don't have a remap with EGR closed you would get a MIL light with that sort of total blank.

If you have a remap with the EGR closed the MAF flow figures should be ignored and you won't get a MIL light with the P1100-P1103 codes normally associated with disconnection or flow rates sensed? Why would you wish to fit a blank if the EGR is closed anyway would be my question? If you go through life with your head in the sand....all people will see is an ar5e!!

"why would you blank if its disabled" , really just as a precaution and help save the valve

blanking keeps the egr clean if you wanted to put back to standard , the blank goes on the inlet side of the egr so keeps the cr@p out of it

the part that suffers with the cr@p is the side with exposed spindle and the spindle hole where the soot gets up in to gear housing

if you get the one with slotted holes its only 5 mins to fit

only possible problem I could see with egr disabled is that the egr cooler may get blocked , but they can be cleaned out by giving a blast out with a steam cleaner

normally its not the splindle in the egr that get sticky with soot , its the soot pushing up in to the gear housing that causes them to play up , the clean cycle really only keeps the spindle clean , ive seen them complete packed solid with soot , I know this as ive taken them apart when we changed them , sometimes when there gone you can see soot around the metal plate that covers the gear coming out round the small bend over tags that hold the plate on

I think the case of having the cleaning cycle still active when egr disabled during running is a two sided one , keep the cleaning cycle and it wears the spindle bush allowing soot into gear housing , or no cleaning cycle and the spindle gets sooted up
blank it and no cleaning cycle could be a better option
