How to check the coolant level in an Audi A4?

I have noticed that my engine coolant light came on in my Audi A4. How can I safely check the coolant level and add more if needed?

To check the coolant level in your Audi A4, start by locating the overflow tank. It is usually transparent and located near the radiator. Make sure the engine is cool before opening the cap, as hot coolant can cause burns. Once the cap is off, you can check the level against the markings on the tank. If it is below the minimum level, you can top up with a 50/50 mix of coolant and water. Remember to properly dispose of any old coolant.

The first step in checking your Audi A4's coolant level is to locate the expansion tank. It is typically near the front of the engine and has a red or blue cap. With the engine off, open the cap and check the level against the markings on the tank. If it is below the minimum, you can add a mix of equal parts coolant and water until it reaches the desired level. Consult your owner's manual for information on the type of coolant recommended for your vehicle.
