What are the common engine problems in Audi A4?

I have noticed that my Audi A4 is not functioning as smoothly as it used to, with occasional hiccups and loss of power. I suspect that there may be an engine issue. Can someone familiar with Audi cars help me diagnose and fix the problem?

The most common engine problems in Audi A4 are related to carbon buildup and timing chain tensioner failures. We recommend using high quality fuel and regularly cleaning the engine to prevent these issues. Also, keep an eye on your car's oil level and check and replace the timing chain tensioner as needed.
