How can I fix the malfunctioning engine in my Audi?

Recently, my Audi's engine has been making strange noises and sometimes even stalls. What could be causing this issue and how can I fix it?

One common issue with Audi engines is a faulty ignition coil. It is best to take your car to a certified mechanic to properly diagnose and replace any faulty parts.

It could also be a problem with the fuel injectors. Try using a fuel injector cleaner or taking your car to a trusted mechanic for further inspection.

Another possibility is a clogged air filter. It is important to regularly replace your air filter to prevent any issues with your engine.
