Audi A3 Oil Pressure Switch

The Audi A3 Oil Pressure Switch serves as the automatic watchdog of the engine and is continuously monitoring the pressure of the lubricating oil and displays the same on the instrument panel to alert the driver when pressure is no longer in the safe range. This small switch is threaded through the block or filter housing, and it has a diaphragm which moves under the oil pressure, connecting or breaking an electric circuit to illuminate the red oil icon. When the pressure is low, it allows the metal components to overheat and bind; when it becomes excessively high, seals may explode, hence the on-off switch is significant in engine life protection. Through all generations of the small Audi hatch and sedan, the fundamental concept has stayed the same, that is, people with any model of A3 will have an identical basic sounding alarm instead of having a variety of models. Although certain recent vehicles use a single sensor to measure the pressure and temperature, the unit that was installed on the Audi line remains a single-use unit whose sole purpose is to provide instant feedback on the oil pressure. Due to the screw-in connection of either a single or twin wire, the replacement process is very fast and cheap, but it is a way to invite massive repair costs should you ignore the warning inside the dash. To the majority of Audi drivers, frequent oil changes serve to make the Oil Pressure Switch respond properly, and it is advisable to make sure that the connector is free of any dirt so that the Oil Pressure Switch continues to transmit its important signal. As long as the Oil Pressure Switch and the warning lamp inform the drivers that the pressure is in good health, they may enjoy their journeys in Audi.
