View Full Version : Vacuum problem

10-13-2013, 08:34 PM
When I was taking my car (99 A4 2.8L) apart... Oh about 2 months ago, a lot of the vacuum tubes snapped... Now that I got my heads back/ installed I got to the "crap" point of, what goes where. I printed off some diagrams from autozone and I really can't trace the routes they are taking. If anyone has some good pics, or info please help me out.

I didn't see much for 2.8... It might be pretty similar but I'm not quite sure yet I am rather tired, gonna go grab some more sleep

I wonder If it is similar enough to go by though?

Does anyone know where the tube goes that branches off the tube that come out oftge intake right in front of the throttle body? I know it has 3 parts that branches off. I need where it goes when it branches off first. It's the same tube that goes through the firewall and into a fairly big black cylinder by the brake fluid resivior. I think it might be the brake booster but I'm not 100% sure. Thanks in advance!!!
