Hi

yes on the pic of the 1994 engine thats the valve (with the blanked off pipe) and short stub at the very top.

The valve lower down with the horizontal lever (as on 1995 picture) is i think the wastegate auctuator for the turbo. The pipe from it should go to the inlet manifold to sense turbo pressure.

The EGR valve when fully connected has a small vacuumn pipe to a eletric solenoid valve (like the cold start system) and is controlled by a relay next to the glow plug controller. Yours doesn't have this as it looks like it was never fitted.

I don't know why Volvo kept the EGR valve in place but blanked off the pipe, unless its cheaper to fit all engines with the valve & disable it for markets that don't use the EGR.

My M reg 1995 model doesn't have the valve at all so who knows.

As the pipe is blanked off, your EGR should be disabled, but perhaps the valve has broken?

Not having one to test, i can only suggest you see if there is any way you can check if the valve is open or closed or maybe remove it and blank off the hole.
