What does the wrench symbol mean after starting a Volkswagen?

[Cardoso]

It is actually quite normal for a wrench symbol to appear on the dashboard after starting a Volkswagen. The wrench is a maintenance indicator, reminding the driver that it's time for maintenance. Vehicle maintenance cycle: The maintenance cycle is preset when the vehicle leaves the factory, so the "small wrench" symbol will appear at certain mileage intervals to remind the driver to perform timely maintenance. Typically, the maintenance cycle is every 5,000–8,000 kilometers driven, while the factory-set cycle is usually slightly longer than 8,000 kilometers. Routine maintenance items: Oil maintenance: Oil, also known as lubricant, helps reduce engine wear and provides cooling and lubrication for the engine. There are three types of oil: Full synthetic oil: Should be replaced every 10,000–12,000 kilometers. If the car is not driven frequently, the oil may emulsify and lose its effectiveness, requiring replacement after about a year. Semi-synthetic oil: Should be replaced every 8,000–10,000 kilometers. Mineral oil: Should be replaced every 5,000 kilometers.
