What are the common electrical issues found in Audi A5?

I have recently bought a used Audi A5 and have been facing some electrical issues. The check engine light keeps turning on and off and the car struggles to start sometimes. What could be causing these problems and how can I avoid them in the future?

Some common electrical issues in Audi A5 include faulty battery, malfunctioning alternator, and defective starter. It is important to regularly check and maintain these components to avoid any problems.

One possible cause could be a loose connection or damaged wiring in the electrical system. It is recommended to have a professional mechanic inspect and repair any wiring issues to prevent further complications.

In addition, using aftermarket electronic accessories or improper installation can also lead to electrical problems in your Audi A5. Always consult with a trusted mechanic before making any modifications to your car.
