    Looking for correct Turbo Inlet Hose

    Guest-only advertisement. Register or Log In now!
    I'm putting my 2002 A4 1.8T Quattro manual's intake back together with appropriate parts due to a running lean issue. I purchased the car with an AFE setup, but wasn't installed properly, and I also noticed some wore out hoses. I got an OEM Turbo Inlet Hose from an '03 A4 1.8T auto fwd parts car, but seems to have an extra hole near the MAF that I can't seem to find that goes to my car. Is there a difference between the 2 years I don't know about?

    Eventually would like to reinstall the AFE, but missing the rubber hose that mounts the intake to the turbo. Original owner clamped the plastic intake to the turbo, but would easily slip off

    This is a picture from the parts car I got the turbo inlet hose from. I don't have the hose assembly circled in yellow

    The 2002 ran the lower block breather (PCV) through the SJP to the intake manifold. In 2003 that was changed and the SJP received a fresh supply line coming from the TIP and the PCV was connected directly to the intake manifold. Thus the extra port on the 2003 TIP.

    Simply plug the hole for your 2002 model.

    Thanks. I did that, but ran like crap. Suppose I'll do a boost/vacuum leak test next.
