i heard that audi warranties last until 80k miles. after that ur on ur own. which leaves me to wonder if my 12 year old second hand audi is still under warranty. i still have the full maintenance record of the owner before me. they took good care of it with frequent maintenance. but now i need new spark plugs, an oil change, and the passenger door won't unlock. considering this, will warranty cover it? is it still under warranty, despite being 12 years old? what dos warranty cover for audi's anyways?
