Puma EGR valve

Thanks fellas, yep, I knew what EGR meant ! I have an 08 Citroen C5 diesel & am also trying to understand it also. The guru mech. who helps me out with that has advised that when I had low speed surge to restrict the ex. gas with a "washer " at the flange to the EGR, that worked. Does anybody know where I might get a s/h nanocom? Not that it makes any diff. but my puma is '10 not '08. Even forget how old I am.Thanks

Hi All
Would someone mind putting up a photo or 2 of the EGR and where to fit the blanking plate. Mine is regularly 12.5l/100km and would like to get it down a bit with a bit better response, especially when towing.
'Thx Ian

Just recently the EGR has gone from the usual "chucka chucka chucka" to louder "clunk clunk clunk" when turning the engine off.
I have also noticed there is bit more clatter when accelerating and also more of a flat spot.

Over the weekend I disconnected the EGR.
The beast is running 100% better and the scan gauge is showing awesome fuel consumption. Compared to my average 11.5 L/100km it's showing sub 9's (not sure how accurate this is).

The engine light is on ofcourse which I can clear with the scangauge.

What I need to know is, is there any long term issues with leaving the EGR disconnected????

Just curious here, but I've heard others installing the blanking plate, but to prevent a code being thrown up, they have drilled a small hole(6-8mm) in the blanking plate that prevents the error code from coming up - anyone heard of this?

I assume the installation of a Catch Can is also recommended as well ??

There are a few threads here abouts on this subject, but one that caught my attention was where somebody mentioned about taking the activating gears out of the egr mechinism, thus the egr motor still opens and closes but not the valve itself and the ecu still recognises that it works acording to how it should, therefore no codes or warning lights show. Then maybe the whole system can be removed :)

It didn't work for me :mad::mad:
Before getting into this trouble(removing gears etc),unplug the egr connector and observe how soon the engine light will lite on the dashboard,usually after 3 ignition cycles,if not,you're lucky,just leave it unplugged..

Where abouts is the plug?

Fatman, when you say trouble do you mean the removal of the gear? As I understand it if you remove the idler gear and leave the egr plugged in the system should not detect a fault. if you simple unplug the egr a fault will be detected. I have watched this topic on different theads for a while. Although I would like a remap if I can disable the egr by the removal of the idler I would be happy with that. Coming from a 300TDI defender the I am more that happy with the puma engines performance. And disabling the egr can only improve that and add to engine longevity.

The Egr valve is number 3, the plug your after is on the flat end.

For the 2.4 egr can be blocked through remap( alive,bas), for the 2.2 nothing really available or proven yet.
