OEM Audi RS4 Fuel Pressure Sensor

This high pressure fuel sensor is located on the fuel rail. It measures the fuel pressure at the rail and sends this information back to the ECU. If a problem arises with the amount of fuel pressure, the sensor will alert the ECU, which in turn, will alert the driver. Usually with a loss of fuel pressure it can be a faulty pressure sensor, a fuel pump, or a clogged fuel filter. Replace your faulty pressure sensor and get your vehicle back to excellent running condition.
