Where exactly is the egr valve on a 94 z28 a4. And how would i go about removing it and cleaning it.

 

I belive it is located on the back of the intake , as far as getting it off and cleaning it ????

 

Rear of the intake manifold, off center toward the drivers side. It is mounted on 2 studs, and has something like 13mm nuts on the studs. There will also be a vacuum line attached to it.

BACK OF INTAKE

Ignore the vacuum line coming from the right side of the intake, that just dropped down off the fuel pressure regulator.
