What are some common mechanical issues in Audi cars?

I have recently purchased an Audi car and I am wondering what kind of mechanical issues I should be aware of. Are there any common problems that Audi cars tend to have? What should I do if I encounter any of these issues?

One common issue with Audi cars is with the ignition coil. If you experience your car misfiring or stalling, it could be due to a faulty ignition coil. It's important to get this checked and replaced if necessary, as it can lead to bigger problems if left untreated.

Another potential issue is with the timing chain tensioner. If you notice a loud rattling noise coming from the engine, it could be a sign of a faulty timing chain tensioner. Get this inspected and replaced if needed, as it can cause significant damage to other engine components if it fails.
