How to check EGR.
Any one any ideas how to check an EGR valve.
I have just replace on my 1.6 XEL to try and stop the old stalling problem.
I have already changed the Air idle valve.
Does the EGR operate as an on/off valve ie fully open or fully closed or does it gradually open depending on what the engine is doing?
When should it be fully open and when should it be shut?
I can see how this icrease revs when the car is coming to a standstill by opening the EGR valve and letting more air(exhaust fumes) Back into the inlet manifold thus increasing the revs.
any help is much appreciated.
Gradually opens chap, the only way to check it fully is with Tech 2 as you can do an acctuator test with it.
If the car feels like its hunting for revs then theres a good chance that its the EGR valve.
Hope that helps mate.
