    Hey guys, new to posting on this forum, but very long time lurker:thumbsup

    I used a DIY to replace the EGR hoses on my 2006 tdi and with great success (the two that conects to the firewall)

    When i took the car for a spin i noticed the coolant leak was still present, but from another hose.
    I searched the net and couldn't be %100 sure on the part or the part number before I go to the local Vdub dealer.

    found a few links but no part numbers. It is the below the EGR and and has a foil wrap around it working its way to the top of the motor (not exactly sure were it ends up yet)

    I found this photo and the hose i need is the one with the arrow on the left pointing to it. Number one on the photo

    [​IMG]

    i also tried cutting the line and reattaching it but still a fast drip coming from the hose

    any help would be much appreciated

    Update.

    I went to a local VW dealer with the picture, and they couldn't be 100% sure what part number it is on the schematic. They want me to bring the car in to get a look at it, but the car is on Jack stands and I'll fix the car.

    The foil wrap thing is the vacuum actuator for the EGR cooler valve. That metal line coming out of it is a vac line.

    I think hose #1 is #24 in the diagram attached. I can't tell you more than that but I'm pretty sure it's #24.

    THanks for the reply, but i already replaced part number 24. it is number 3 on the photo i posted is the pipe i replaced. comes in a set with another pipe.

    Number One in the photo i posted is the pipe i need. it has a heat shield wrap around unlike the parachute cover over the EGR cooler valve.

    Bump :)

    after looking at the car, i can be certain it is part number 20.

    comes from the top rad hose, and a union that connects to the motor, than snakes down to the EGR cooler.
