How to check for a blown head gasket in an Audi A2?

I suspect my Audi A2 might have a blown head gasket. What are some signs and symptoms I can look out for?

One of the most common signs of a blown head gasket is white smoke coming out of the exhaust. So if your Audi A2 is emitting an excessive amount of white smoke, it could be a sign of a blown head gasket. You should also keep an eye on your engine's temperature and oil levels. If the temperature is constantly high and the oil is milky or grayish in color, it could be a sign of coolant mixing with the oil due to a blown head gasket.

Another way to check for a blown head gasket is to do a compression test. Using a compression gauge, you can test the compression levels of each cylinder. If one or more cylinders have significantly lower compression than the others, it could be a sign of a blown head gasket. Additionally, you can also check for bubbles in the coolant reservoir, which could indicate exhaust gases leaking into the cooling system.
