Why is my Audi A6 making a clicking noise?

My Audi A6 has started making a clicking noise whenever I accelerate. It seems to be coming from the engine. It's been serviced recently, so I'm not sure what could be causing the issue. What should I do?

It sounds like you may have an issue with your engine's timing chain. This can cause a clicking noise when it becomes loose. I would recommend bringing your car back to the shop where it was serviced and explaining the issue. They should be able to diagnose and fix the problem for you.

Another possibility could be a loose or worn out belt. This can also cause a clicking noise when the engine is running. I would suggest checking the condition of your belts and if necessary, replacing them. This is a fairly easy and inexpensive fix that you can do yourself.

If neither of these solutions seems to be the problem, it's possible that there is an issue with one of your engine's components. It's best to take your car to a trusted mechanic to have it checked out further. They will be able to pinpoint the exact cause of the noise and recommend the best course of action.
