    The pipe between the turbo outlet, intercooler and intake manifold has become detached resulting in an air leak and loss of power.
    There may also be MIL on condition.

    1. The hose clamp was not correctly positioned during the assembly process.
    2. There was inconsistent wall thickness on the rubber hose.

    Continuous improvements are being made to the parts and the vehicle assembly process.

    Market Treatment
    To prevent subsequent failures of the hose joint, the bulletin repair method must be followed in the case of a disconnected intercooler hose joint.

    Repair Method
    1. Using brake cleaner or degreaser, thoroughly clean and dry the clamp, pipe and rubber hose to remove any oil residue.
    2. Make sure there is no oil on your hands or gloves which could contaminate the joint or the outside of the hose.
    3. Refit the hose and clamp ensuring the hose is pushed fully against the shoulder on the pipe. Do not use a lubricant to assist with assembly of the hose onto the pipe.
    4. Slowly tighten the clamp whilst checking that:
    i) the clamp is aligned at 90º to the centre of the pipe.
    ii) the clamp is more than 5mm from the end of the hose.
    iii) the paint line on the clamp is completely covered by the tail.
    Photograph 1 shows correct installation: clamp aligned at 90º to centre line of pipe and more than 5mm between the edge of the clamp and the end of the hose and clamp tail is covering the paint line.

    The following photographs show incorrect clamp installation. Clamp is not aligned at 90º to the centre line of the pipe.


    Clamp is less than 5mm from the end of the hose.


    Clamp is not tight enough. Paint line is not completely covered by the tail of the clamp.


    If you inspect a vehicle which has been driven for some time you may see there is a gap between the end of the hose and the shoulder on the pipe. This is not a fault. Under normal conditions, the hose will move on the pipe due to engine vibration and air pressure.
