How do I check the coolant level on my Audi A2?

I recently bought a used Audi A2 and want to make sure the coolant level is correct. Can someone explain the process to me?

First, wait until the engine has cooled down and locate the coolant reservoir near the front of the engine bay on the passenger side. The container should have a min and max mark on the side. Remove the cap and check the level. If it is below the minimum mark, top it up with a 50/50 mixture of coolant and water.

A low coolant level could indicate a leak in the system. Make sure to also check for any visible leaks or puddles of coolant under the car. If you do find a leak, it's best to get it checked and fixed by a mechanic to prevent any further damage to your car.
