    Battery light and temp warning light on no one mentions to first check to see if the belt driving the alternator is still on.

    I just got a new key from the dealer , key plus Audi needs to program it at a cost of $400 ,car starts with new key but does not operate door locks they told me it would be too expensive to diagnose that problem.
    Thanks for the info on here I came home and programmed the keys myself and door locks work and alarm sets, my car is a 2004 A6 and I guess the dealer has forgotten how to work on them.

    Hey Jims,

    Wondering if I could get your opinion I have a 2008 A4 and I just swapped out the alternator as well as bought a new battery for it and it won’t start up as well as loses power after no more than 20 minutes of driving when I jump start it. I was going through the wiring and noticed that the part of wiring that bolts on to the alternator is chipped.. Could that be the issue or is that not significant enough?

    This article is a good resource but just to add a few points here. One of the most common ‘battery problems’ is simply a battery that is past its prime and needs to be replaced.
    If your battery is a couple of years old, do not try to ‘fix’ it.. instead buy a high-quality battery that can last you a couple of years.

    If a new battery is not working and the battery light indicates a problem, FIRSTLY check if the battery is under warranty and there are no problems with the Unit. If it is in good condition, the next possible outcome is usually a bad alternator and poor connections.

    You can fix these yourself at home as even taking it to a dealership won’t cost you less than a 100 bucks.
