What are the most common issues faced when driving an Audi A6?

I recently purchased an Audi A6 and noticed some issues while driving. Can an experienced Audi owner shed some light on the common problems faced while driving this car?

One of the most common issues with Audi A6 is the suspension system. It may start making noise or feel bumpy while driving. The best solution is to get it checked at a certified Audi service center.

Another issue I faced while driving my Audi A6 was the engine light turning on. It could be an indication of something more serious, so it's best to get it diagnosed by a mechanic.
