    how to remove intake tube for changing turbo coolant/oil seals

    Guest-only advertisement. Register or Log In now!
    :( okey so i wanted to renew the seals on my turbos for coolant and oil. Sadely dealer didnt provided the correct coolant inlet seals but will get it sorted. But i was checking how the hell one removes the bolt holding the outlet pipes?! It is burried deep between the intake pipes. I guess removing the rubber connection hose (turbo/throttle body) but then i still can reach the secobd bolt op the intake pipe on the left side (if you stand in front of engine). How the hell designed this stuff :s....

    Removing the throttle body will allow you to then access and remove the turbo inlets. Once the turbo inlets are removed, you should be able to access the bottom connections of the coolant and oil inlets.

    The oil separator might make things difficult for you. If you still cant gain enough access, the only way tonremove the oil separator is to take off the front bumper, crashbar, and headlights, which will allow you to move the radiator housing forward a bit, so you can then remove the bolts holding the charge air cooler housing, which has the oil separator attached to it. Congratulations! If you’ve made this far, you can now easily change the turbos as well, since you have perfect access to them.

    I haven't brought my S6 in for the (TSB) replacement seals. Are they replacing the bottom ones too? I was under the impression that only the seals at the turbo itself are being replaced.
