Why does my Audi A1 have low tire pressure?

I noticed that my Audi A1's tire pressure is often lower than recommended. Is this normal, and what should I do about it?

It is normal for tire pressure to decrease over time, particularly in colder weather. It is important to regularly check and adjust the tire pressure to ensure safe and efficient driving.

Low tire pressure can also indicate a puncture or leak in one of the tires. It is recommended to check for any visible damage and have a professional inspect the tires if needed.
