What are some common issues with Audi engines and how can they be resolved?

I recently saw a warning light on my Audi dashboard and I'm worried about potential engine problems. What are some common issues with Audi engines and how can they be resolved? Is there anything I should do to prevent these issues?

First, it's important to regularly maintain your Audi and get any necessary repairs done as soon as possible.

One common issue with Audi engines is oil sludge buildup. Make sure to regularly change your oil and use high-quality oil to prevent this.

Another issue is with the timing belt. It's recommended to replace it every 60,000-90,000 miles to avoid potential engine damage.
