How can I fix the heating issue in my Audi A2?

I have noticed that my Audi A2 is not getting warm enough even after driving for a while. What could be causing this issue and how can I solve it?

One possible solution could be to check the coolant level in your car. If it is low, it can affect the heating system. You can top up the coolant if needed and see if that fixes the issue.

Another thing to check is the thermostat in your car. A malfunctioning thermostat can prevent the engine from reaching the proper temperature, which can affect the heating system. Get it checked and replaced if necessary.
