If you drive a Volkswagen car with a faulty Oil Level Sensor, it can lead to serious engine trouble. Without accurate readings of the oil level, your engine could run low on oil, leading to extensive damage. The oil level sensor is designed to alert you if the oil level is low, so if it’s not functioning correctly you won’t be aware of the issue until it’s too late. Low oil levels can trigger a number of issues such as reduced fuel economy, increased emissions, grinding and knocking noises, increased engine temperature and accelerated engine wear. These issues can be extremely expensive to repair, so it’s important to ensure the oil level sensor is in good working condition in order to avoid any costly problems.
