Audi Repair Questions? Ask a Mechanic for Answers ASAP
Hello. My name is ***** ***** I will be attempting to help you today. Was the vehicle dying while you were driving? If so, sounds like you have a charging issue. Here is you battery location and removal instructions..
My advice would be to test the alternator and the battery. If it is the alternator, I usually replace the battery along with it. My theory is they should come in pairs.
Was your dash battery light on?
I'm inclined to believe that you may need to replace your alternator. Once you get the vehicle started, you can test the voltage output. It may only be partially charging the vehicle, so when the demands for this extra power arises, the alternator can't produce what is asked for leading to your failing battery. The alternator should be pushing no less than 13.5V.
If you have any other questions on this subject, feel free to ask. If that will be all, a positive rating would be greatly appreciated. Thank You.
