N12 Turbo Forums

Hi
Just bought an 1983 N12 E15et
I have found a vac pipe that that comes from the inlet manifold ( next to the brake servo pipe )
It is a length to reach the dizzy , and is blanked off with a very rusty screw driver. Any ideas on where it’s destination really should be ? Many thanks .

not with my car at the moment but pretty sure that vac hoses either goes to the throttle body or the boost gauge sensor on the firewall.

Hey mate does this help you? vac line from manifold goes to boost gauge sensor. Vac line from next to fuel rail goes to throttle body
