Hey, since my Cali has now fallen the crack dead for sacrifice. I need a new one. But since I don’t really like the original. I thought of a chic fan manifold. But there is no such thing as an EXCLUSIVE connection for the second air pump. Now I have the following questions: Can you leave the pump out? Is it attached to the AGR or is it simply screwed with a fixed device? Does the car still get its AU when it is gone? What does the motor STG say if the w eg is ? Thanks for your answers
