EGR valve V40 1.9 td 1998

[wints]

Has anyone wrote a guide to the cleaning / blanking off of the egr valve on this engine ?

I've seen the various posts by members, especially the very informative one from Biotoxic, but none are specific to my model.

I think that I'd prefer to put a blanking plate in, but I think I'd need a bit more guidance, pictures etc. And I'm assured that the plate would not interfere with the vehicle emmission warnings because it's not a 'cdi' model.

Its in the guide section, only held on with 3 bolts, just keep it in there else it will throw a code, not really an issue.

Hi, the older engines (F8QT) do not have the cartridge type of egr valve that the last link takes you to. Up to 1999 they have vacuum type of egr valves. This link below shows a blown up drawing of the egr system in a pdf file ( for a Mitsubishi, but is the same Renault engine) at section 11A-11-1. They do not have problems with any fault codes/lights when blocked off.

Just drifting a tad off the thread, but I will have to get my EGR done soon for my P2 (115 hp) 1.9D and I would like to know what members think the chances are of the EGR valve being damaged during removal if it gets tricky to remove by using a piece of wood and hammer and a pipe wrench has to be used.
If there is a risk of damaging the valve, I will order a new one as a precaution and then return it if all goes well, also does it make sense to fit a new one anyway to save time or a possible future failure.

Hi, if yours is the cartridge type of valve, then yes they can get stuck in, but removing it should not brake it. The valve can also be put back in with it turned 180 dec ( ie 12.00 o clock to 6.00) with will block it of. This link would be helpful, how to remove, clean, and rotate.

I've removed a few EGR's todate and have never had one breaking. One of the EGRs I removed was from the car of another member here and it was completely covered with soot everywhere. A bit of carb cleaner sprayed via the manifold will wet/lubricate the soot and it will be easier to rotate. If you ask me honestly, you don't need that much force to rotate it. The main problem rotating it is that you have an extremely small area to apply your force and your hands could not possibly do that. That is why the pipe wrench comes handy as it can just about grip on the edges of the inner EGR and once you have a good grip, you will find that you will manage to rotate with little force. Hope this makes sense

Thanks Gatos,
So there is no need to order a new one, as I was just concerned that the pipe wrench might deform the case and stop the valve seating correctly or jam it in one position.

As long as you are careful, you will be fine. Make sure you remove the outer part of the EGR first and then use the pipe wrench to grip the 1-2mm edge of the inner part of the EGR. And worse comes to worse, you still have the inner part of the EGR I've sent you....
