Audi A5 2.0 TFSI Electrical Malfunction and Error Code P0C94

Hello everyone, I own a 2012 Audi A5 with a 2.0 TFSI gasoline engine and it has 200,000 km on it. Recently, I've been experiencing a general electrical malfunction and received an error code P0C94. I'm trying to figure out what the issue might be. Can someone help me diagnose this problem? Any advice or guidance would be greatly appreciated. Thank you!

Start by checking the battery and its connections. Ensure the battery terminals are clean and tightly connected, and test the battery voltage to confirm it's in good condition. A weak or failing battery can cause electrical malfunctions. Let me know how it goes or if you have any further questions!

While waiting for the battery test results, inspect the alternator belt for wear or damage, as a faulty alternator can also cause electrical issues. If the belt looks fine, consider testing the alternator output to ensure it's charging the battery properly. Let me know if you need further assistance or have any questions!
