    Audi a4 b7 wastegate help

    Hi everyone I bought a project b7 2.0t with a broken timing belt, everything went well.now as I was inspecting the turbo before I install it . I applied pressure to the wastegate and the wastegate slowly creeps back.is it suppose to? Or is it suppose to hold? I used a hand held vacuum pump .I also made sure connections were tight . Ty so much and have a great day😊😊

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    The wastegate should have held the pressure in my opinion because the system dumps/vents that pressure back off via N75.

    Hi audi4ever,
    Are you sure your vacuum pump is ok and holding vacuum?

    You could connect it to a low pressure gauge and see what happens.
