What is the common problem for Audi A4 engine?

Is there a common problem with the Audi A4 engine? I've asked around and some people say it's the timing chain while others say it's the oil consumption. Can someone please give me some insight on this? Thank you!

Hi Emily, the common problem with Audi A4 engine is the timing chain. If not properly maintained, it can stretch and cause major issues. Keep an eye on your engine and make sure to change the timing chain before the recommended mileage to avoid costly repairs.
