How to disassemble the head of Audi a8l mechanical booster pump?

Remove the booster belt, remove a circle of screws, and remove the intake pipe in front of the throttle!

1. First of all, you need to lift the car with a lifting frame, remove the lower engine guard and drain the antifreeze. After opening the air duct, unscrew the muffler screw so that the muffler and the exhaust pipe are staggered. Loosen the fixing screw of the oil pipe, and do not unscrew it completely.

2. Put the car down from the lifting frame, remove the hood, disconnect the positive and negative poles of the battery, and remove the air filter. Then take the oxygen sensor out of the bracket and unplug the connector. Unscrew the fixing screw of the crankcase exhaust pipe from the turbocharger.

3. Disconnect the connector between the pressure regulator and the turbocharger, loosen the screw and push the three-way catalytic converter backward, then remove the heat shield. Unscrew the screw of antifreeze oil return pipe, and remove the oil return pipe and oil inlet pipe. Finally, open the antifreeze inlet pipe and take out the turbocharger downward.
