Audi a8-replaced battery---trunk lid button and gas door release won't work

SOURCE: i can't open the lid

I had a similar problem with my TT Roadster and it was a problem with my central locking system, it temporarily disengaged after a minor incident with the rain while my top was down. Anyway for me it was simply a matter of time before the system reengaged it's self it took maybe a week or so, but to get around the problem, behind your passenger seat there is a storage compartment, pull the lever in the storage compartment to open the trunk, once in the trunk on the left sidewall of the trunk there is a seamless square open that square and there is a black pulley in there, pull on that and your gas tank should open. I hope this help.

Fold down rear seat and climb in the trunk....there is a manual release at the center of the trunk lid. (mandated by the government to kids don't get trapped in the trunk).

Hi, yes there is. To release the trunk - look on the centre console, just rearward of the front seats and you will notice a separate rectangular section in the plastic, if you lift this out you will find a cable release for the trunk underneath. To open the fuel filler cap manually, look inside the car just behind the rear light on the same side as the fuel filler and you will notice a flap in the interior trim, which is to allow access to the rear lamp. Open this and then looking towards the top you should see a loop of orange plastic - pull this towards the rear of the car to release the fuel filler.
Hope that helps Matt..

check the fuses, if you can get into the trunk with the key then there should be a cable or some short to pull to open the gas cap door
