I have a 2015 Audi A4 and recently it has been making strange noises and occasionally sputtering. How can I determine what is causing these issues and how can I fix it?
ReplyFirst, check the engine oil and coolant levels to make sure they are at the required levels. Then, use an OBD2 scanner to check for any error codes stored in the engine's computer.
If the scanner shows any error codes, look them up online to determine the possible causes. If there are no codes, it could be a problem with the spark plugs or ignition coils.
Another possible issue could be a clogged air filter or a faulty fuel pump. Make sure to check these components as well.
