i just resently purchased a 95 tsi awd and the vac lines were all disconnected...so i reconnected everything as the vac. diagram shows and noticed the purge control valve is missing according to the diagram? according to the autozone website the pcv valve (which i assumed was the purge control valve is located "under hood, driverside, rear engine area, mounted on top rear of camshaft cover") and in the diagram the purge control valve which looks nothing like the pcv valve i purchased 4 the car is located under the battery mount http://autozone.com/az/cds/en_us/090...rInfoPages.htmso is the pcv valve and the purge control valve 2 different things? and where can i find a purge control valve if so because none of the auto parts stores around my area have them
