Genuine Audi A3 Vacuum Pump

The Audi A3 Vacuum Pump delivers the necessary vacuum that the diesel engine or a direct-injection gasoline engine cannot achieve on its own, thus giving the engine good power-assisted braking and good performance of the HVAC flaps and emission control. Since contemporary Audi diesel engines do not have a throttle plate, there is no vacuum in the manifold when they are in normal operation and therefore the vacuum in the manifold is supplied by the Vacuum Pump. This component is mounted on the cylinder head or camshaft and pulls air through the brake booster until about 12 psi of negative pressure is reached, after which drivers can tap the pedal with very little effort. It also supplies vacuum to turbo actuators, secondary air valves, and cabin ventilation doors, which provide smoother acceleration, cleaner emissions, and steady climate control. Earlier designs applied a diaphragm-type or piston-type Vacuum Pump that was mechanically driven by the camshaft and was limited only by engine speed. Subsequent designs transitioned to smaller rotary vane units attached to the end of the camshaft, with some efficiency versions also using an electric Vacuum Pump that is operated only when the engine is not under vacuum, reducing the load on the engine and providing a small dollop of extra power. Throughout the second-generation A3 diesel range, the transition to the vane design was the norm. Some Audi power units go so far as to combine a tandem fuel and vacuum system to reduce space usage. Whichever style it is, Audi engines direct engine oil via the pump; thus, it is prudent to replace it when engine parts have been seriously damaged and debris has scattered. Maintaining the pump in good condition maintains brake feel, safeguards the emissions devices, and ensures long-term reliability, which Audi customers value.
