The electricity for the fuel pump in an Audi A3 typically comes from the vehicle's battery and is routed through the fuel pump relay. When the ignition is turned on, the relay activates, allowing current to flow to the fuel pump, which is usually located inside the fuel tank. Additionally, the fuel pump is controlled by the engine control unit (ECU) to ensure it operates at the correct times during engine operation.

In an Audi A3, the fuel pressure sensor is typically located on the fuel rail, which is situated on the engine. It monitors the fuel pressure and sends that information to the engine control unit (ECU) to ensure optimal fuel delivery. In some models, it may be found near the fuel pump in the fuel tank. Always refer to the specific service manual for your model year for exact locations.
To remove the petrol filter on an Audi A3, first ensure the vehicle is parked on a flat surface and the engine is cool. Relieve the fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls. Next, locate the fuel filter, typically found along the fuel line; disconnect the fuel lines using appropriate tools, and then unbolt or unclip the filter from its mounting. Finally, replace it with a new filter, ensuring all connections are secure before reassembling and reinstating the fuel pump fuse.
