Basic boost pressure control valve setting: Notes
The wastegate's diaphragm unit is adjusted at the factory and should therefore only be adjusted in connection with repair or change of components. After any adjustment the basic charging pressure should always be checked, see ADJUSTING THE BASIC CHARGING PRESSURE .
IMPORTANT:
When adjusting the pushrod stroke, it is important that the pliers used as support are positioned as close to the threads as possible. Turn the end piece so that no burrs are created on the pushrod. Adjusting must always be done with the pushrod disconnected from the operating arm.
