my 2008 Audi tt quatro 3.2 has an extra wire coming out of the battery that my new battery doesn't have. what is this?
1 Answer
did you buy the battery from an audi dealer ? if you did not take the battery back now and go there instead. cause for 1 you get better quality battery that way. and 2 they give you the correct battery for your car. and 3 they sell them with a direct swap for cheaper then most battery places.
