Mein Auto: 1993 325is
I have a 93 325is, and I was able to remove the ICV by removing the air box and assorted components. Rather than mess with removing the 2 hoses from the ICV itself, I just disconnected the long hose from the bottom of the accordion plenum going to the MASS sensor.
The other thicker (ridged) hose connects to a plastic fitting which goes into the inside area of the manifold. I pried this fitting off and presto, the whole icv came out, hoses and all.
UNFORTUNATELY, There is a clip at the bottom of thas plastic fitting that holds it onto the manifold... I broke that clip when pulling it off the manifold. Now I have to order a new part.

My car was pulling code 1222 - Lambda. Indicative of a vacuum leak. Sure enough, that long ICV hose was cracked wide open.

To the OP- if your car is a 325 6 cyl- just connect the hoses to the ICV first, put it into place and connect the hoses to the points I mentioned after it's all in place.
