I've removed the EGR valve from my 206 after the RAC man checked the fault code when the engine warning light came on. I've thoroughly cleaned it including putting it through the dishwasher twice (don't tell the wife) but i can't seem to blow into it. It lets a tiny little bit of air through when i blow really hard but not a lot at all.

Is this normal? I don't want to replace it only to get the same problem and have to take the car apart again!

Thanks for your help.

Paul.

Update - found this thread in case anyone else wonders if this is normal. Turns out it is. If you suck through it and depress the piston then it lets the air through

You have the older mechanical (diaphragm) type. It is operated by engine vacuum. It should be closed by default because the diaphragm is being pushed down by a spring thus pushing a pintle down into a pintle seat closing the passage. It is opened by engine vacuum when the vacuum overcomes the force of the spring. When opened the passage will also be opened allowing some of the exhaust gases to be recirculated back into the intake manifold and mixed with air to be combusted for a second time. You should be able to open the pintle and thus being able to both blow and suck air through the passage when you apply enough vacuum to the port on the diaphragm house.
