Driving a Volkswagen car with a Oxygen Sensor problem can be detrimental to the engine and result in more serious, costly issues further down the line. The Oxygen Sensor is responsible for calculating how much fuel should be added to the engine, and if it isn’t working properly, this can lead to a rich air-fuel mixture. This means that the car is getting too much fuel and not enough air, which can cause the engine to work harder than it should and potentially cause damage. Not only can this lead to decreased performance and fuel economy, it can also create conditions in which carbon deposits can form on the valves and pistons, cause excessive exhaust emissions, and lead to engine stalling or misfiring. It’s important to get this problem resolved as soon as possible before further damage is done.
