How is a chain-driven vacuum pump fitted to the engine to provide proper engine vacuum to the brake vacuum booster in six cylinder engine on BMW X3?

For establishing an adequate engine vacuum to the brake vacuum booster at all engine speeds, there is an induction driven vacuum pump fitted to the engine, located beneath the intake manifold on the front left side. BMW has indicated that the sprocket center bolt must be loosened while the sprocket is immobilized which is best done by use of BMW special tools. First take out the engine drive belt followed by the drive belt tensioner assembly. Loosen the sealing cover for the vacuum pump with the help of a screwdriver from the front side of the engine so as to reach the sprocket. Second, take away the intake manifold. For normal direction of engine rotation turn the center bolt of the vibration damper until the holes in the sprocket match the position of the pump bolts. Mount BMW special tool 114362 to the engine and engage the sprocket with the engine and secure it by using BMW special tool ref 110290. Loosen the sprocket mounting bolt and later on the pump mounting screws, and ensure that the pump does not drop. Last but not the least, pull out the vacuum pump toward the rear, and while installing it, just reverse the above-stated procedure and install the gasket.

BMW X3 Vacuum Pump

The BMW X3 Vacuum Pump provides constant negative pressure so that the SUV's power brakes, turbo controls, and HVAC actuators will operate reliably. Its diesel or direct injection engines are unable to create manifold vacuum by themselves. Early X3 versions included a camshaft-driven diaphragm or piston style Vacuum Pump that shared engine oil and moved with every crank revolution, providing suction to the brake booster and HVAC doors. As the platform was refined by BMW, later models of the X3 switched to a compact rotary vane Vacuum Pump installed at the camshaft end, which provided greater flow with less internal wear. Some gasoline trims eventually switched to an electric Vacuum Pump that would only be activated when sensors detect low pressure to save fuel and reduce noise. Regardless of the style, all BMW X3 units aim to reach approximately 12 psi negative pressure that is sufficient for emissions devices such as EGR valves and turbo wastegate regulators. The main differences are in the drive method; mechanical pumps use engine rotation, whereas electric versions drive independently, and in their internal mechanism, vanes are applied instead of diaphragms for smoother output. Owners should keep in mind that engine damage or oil contamination can quickly ruin the BMW Vacuum Pump, so replacing it when doing major repairs will help keep brake feel and X3 safety at a good level.
