Maintenance for the Volkswagen Passat Engine

I have a 2015 Volkswagen Passat and the check engine light has been on for a week. What could be the possible cause and suggested maintenance?

It is possible that the check engine light is on due to a loose gas cap. Try checking and tightening the gas cap before taking it to a mechanic.

Another common cause for the check engine light to be on is a faulty oxygen sensor. It is recommended to get the sensor replaced as soon as possible to avoid any damage to the engine.

If the check engine light is blinking, it is a sign of a more serious issue such as a misfiring engine. It is important to get it checked by a professional immediately.

Regular maintenance and servicing of your Volkswagen Passat is crucial for avoiding any potential issues. Make sure to follow the recommended maintenance schedule provided by the manufacturer.
