Why is my Audi A4 displaying a warning light?

I noticed a warning light on my Audi A4 dashboard and I am not sure what it means. It's a circle with an exclamation mark in the middle. Can anyone help me understand what this means and if I need to take my car to the mechanic?

That warning light is indicating an issue with your tire pressure. It's important to check your tire pressure regularly to avoid any potential problems. You can easily do this yourself with a tire pressure gauge or have a mechanic do it for you. If the light persists, it's best to take your car to a mechanic to have them check for any leaks or damage to the tires.

I've had that warning light appear on my Audi A4 before and it's usually due to low oil levels. Check your oil dipstick and see if it's below the recommended level. If so, add more oil to your car and the warning light should go away. If the light continues to appear, it could be a sign of a bigger issue with your engine and it's best to take it to a mechanic for further inspection.

The warning light on your Audi A4 could be related to a malfunction in the engine. I recommend taking it to a mechanic for a diagnostic check to pinpoint the cause of the warning light. It's always better to catch any issues early on before they become bigger and more expensive problems.
