Vacuum Diagram for MK4 1.6 motor

Post by Jetta16v »

Hey guys,

Does anyone know where I can get a vacuum diagram for the 1.6 AKL or AVU motor? Need to try and sort a vacuum leak/issue out on the car but cant seem to find anything.

TIA

Waste pomp? Die secondary air pomp ding? Ons sit nie als terug op die motor nie. Ons het die EGR ens af gehaal.

:twisted: nevermind. I read diaphragm. Not diagram. Have never looked for one. Surely there can only be a few connections there.

Haha! Thanks!

There arent many, but would still like to know if we connecting them up correctly as the car is idling and revving very lumpy.

Problem is we don't know where all vacuum pipes are or where they all need to go, The bay was stripped when we got the car

When you turn the car off you can hear air blowing from various areas in the bay for a few seconds
