Checking the Adjustment Of the Boost Pressure Control (BPC) Valve
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the heat shield from the exhaust manifold.
- Turn the setting screw on special tool 9995766 clockwise until the pressure in the table is reached. Measure the stroke length of the pressure servo. Use a vernier caliper
- The measured value represents the opening of the boost pressure control (BPC) valve, measured at the end of the lever (A).
NOTE:
Ensure that the valve is closed when the push rod is in the resting position.
