Trunk won,t open so I can get to boot to open mu gas tank

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.

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..

I can't promise it, but in my 99 A4 there is a release cable in the trunk. I have to pull the trunk carpeting away on the side where the gas filler door is, and there's a red cable there that can be used as a manual release. I imagine your TT has one as well - look in the hatch on the side with the gas door, and pull the lining back - you'll probably have a release cable as well.

Take your key and go to the drivers door, make sure the door is unlocked by pulling on the handle, open and close the door. Insert the key and "lock" the door, double check that it is locked by pulling on the handle. Insert the key and "un-lock" the door, use the handle to open the door and now press the fuel door key and it should open, same for trunk release button.

Audi's are a strange breed, sometimes you just need to "re-set" some stuff. But in the future if you lock the car with the key, the fob will unlock the car but the three buttons in the console will not work, the fob will function correctly.

I hope this helps.
