I can't find good pictures or repair procedures for you. I am almost certain the EGR valve on the 1.8L is at the back of the engine toward the firewall, next to the rubber boot coming from the air filter housing you have the throttle housing and just further looking left (looking in from the radiator) is the EGR. There is usually a vacuum modulator and or an electrical solenoid to transfer vacuum.
