I just looked at my Haynes manual, what a POS! It doesn't say how the controller, mounted on the radiator, works. Just that there are 2 hoses, but it doesn't say where they go.
Did you clean the plug at the controller with a tooth brush and electrical contact cleaner?? It could be that one of the hoses is cracking and letting air in, causing low pressure?
You know if you go to a dealer, he will probably replace the controller $$.

Klaus,
Thanks for the fyi. I don't have a haynes manual and have no idea where the plug and controller is , but we'll check it out. I noticed that after reseting the codes and drive the car for about 20 miles or so, then 241 code shoots back in....so there really is a problem.

Isn't that turbo boost pressure fault? Does your car drive okay? I think you might need to check the boost pressure with a gauge, or take a chance and replace the pressure switch.

Sorry Paul,
His car has no turbo. The EGR flow is too low (241) whatever that means. I cant find that one in my Haynes.

ohhh, then I guess his egr valve is not opening or the pressure switch that confirms the egr has opened is non-functional. I know you cleaned the egr, but that doesn't mean it's working properly. It could also be a wiring problem to the egr. Does the egr receive 12 volts during normal (warm) driving?

Or he has the wrong OBD2 code.

thanks for the reply PBH, Klaus is right my car is non aspirated ( non turbo)
can you pls tell me how to check the voltage? I have no idea.

thanks again,
