Where can I get a microfiche for a 2004 Vauxhall Vectra? I want to replace my EGR valve.
Where can I find a microfiche for a 2004 Vauxhall Vectra 2.0-litre diesel? I'm trying to see the pipework for the EGR system. My local Vauxhall dealer wants nearly £400 plus fitting for an EGR valve, and I want to by-pass this if I can.

Sorry, I don't know where you'll find a microfiche. However you can blank the EGR valve off. In addition, i have copied and pasted this from the Vauxhall forum,which may be very useful.
"The EGR valve is the round unit that sits in front and below the leak-off pipes. The large 3-inch charge pipe connects below it. The EGR has a small pipe connected to it and runs to a solenoid near the battery.
Remove the EGR with the two screws. You may find it is full of oily coke (mine was very dirty). Give it a good clean (it takes a while). Also take off the charge pipe and give the inlet a clean up and flush. Petrol and de-carb can be used to clean these parts, and I found an old toothbrush useful for this. The EGR has a small rubber O-ring gasket. I was not able to source one of these as Vauxhall do not sell them separately.
The result should be better starting, smoother running and more MPG!"
