Audi Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** for the question. If the vehicle is starting and running fine then the charging system and alternator should be fine. If the battery is dying over night then the battery itself should be tested for a shorted cell. A bad battery can cause this. If the battery is fine then you may have bad terminals on the cables or something is not turning off over night and a parasitic battery test needs to be performed.
If the battery is dead then you should have it tested for a bad cell. The battery may be the main issue. As for something staying on, there may be a circuit not turning off properly which is draining the battery. The test I mentioned is done with an amp meter at the battery whic helps identify this circuit issue. Most technicians can do this test.
It can be anything from a light, to the radio, to the ignition. I am not referring to any one area. There are hundreds of circuits that can cause this. The test helps to isolate it.
