What does the yellow warning light on my Audi A3 mean?

I recently noticed a yellow warning light come on in my Audi A3. Does anyone know what it means and what I should do about it?

The yellow warning light is indicating an issue with your engine. It could be due to a variety of reasons, such as a faulty sensor or a problem with your fuel system. I would recommend taking your car to a mechanic to have it checked out as soon as possible.

The yellow warning light could also be signifying a problem with your emissions system. It's important to have this looked at as soon as possible, as continuing to drive with a faulty emissions system can lead to more serious issues down the road.

In some cases, the yellow warning light may simply indicate that your Audi A3 is due for a routine maintenance service. Check your owner's manual for more information, or consult with a certified mechanic to determine if this is the case.
