What to do when my Audi A4 engine starts to make a ticking noise?

I've noticed that my Audi A4's engine has started making a ticking noise. Should I be concerned about this and what should I do to fix it?

Based on your description, it sounds like your engine may be experiencing an issue with the valvetrain. It's best to avoid driving the car until you can have it looked at by a certified mechanic. They will be able to properly diagnose and repair any potential issues.

A ticking noise can also indicate low oil levels or dirty oil. I suggest checking your oil levels and if they are low, make sure to top them off with the correct type of oil. If the noise persists, it's best to have a professional inspect the engine.
