Question about 2003 Volkswagen New Beetle Convertible
FIRST!! Make sure you use an alternate power source before ever disconnecting the battery on any VW that has a built in security system. If you don't you will experience lots of grief that is avoidable.
did learned the hard way and it is not worth it, especially for those people that did not take care in saving their VW's owners manual that has a section about how to reset the security code on the Radio. If you get stuck in this situation you have two options, you can either get the correct tools and pull the radio (the codes are on the top of the unit) or make a trip to the dealer so they can look it up for you based on the VIN for a fee.
HOW TO START OUT RIGHT - Get a alternate power source unit from the dealer (I think Harbor Freight has them too) or make your own using a 9 volt battery or any battery close to 12 volts. Get yourself a cigarette power adapter from radio shack or harbor freight and make two leads off of it with alligator clips on the end following the color codes on the plug. . Red for Positive and Black for negative. Then plug the cigarette adapter into the orifice in your console marked POWER Outlet and connect the clips to the correct sides of your 9 volt battery (or other). Now you can remove the battery without loosing everything. Some forums also say that this will also cause problems with the programming for your injection if an alternate power source is not used. I did not notice a difference in power, however I did get a "running lean" code right after my mishap that did not fire off an idiot light but I truly believe if I had not reset mine I would have caused engine damage resulting from scoring due to the lean condition.
Note - Make sure not to let the positive battery cable touch the inner fender or core support. This grounding will ruin your attempt to do it right. Simply slide an old glove over the positive cable while transfering batteries so it's isolated.

SOURCE: 2003 VW Beetle battery drain
I think I remember running into this once before and found a factory rear speaker amplifier in trunk that stayed powered on then we replaced the amp and the new one did the same thing . then checked radio coding and it wasn't set to proper code so it didn't know to turn off the amp. changed the coding to correct setting and bingo problem solved. hope that might help but coding can only be done by dealership.

Disconnect your negative battery cable. Locate and remove the screws that hold your interior door handles in place (they may be hidden by snap in, or snap on clips). Remove the interior door handles, then disconnect the wire clips to the switches. Your panel is held in place by snap in clips; use a small pry bar to pull them from the door (try to get as close to, or directly under the clips to prevent them from tearing out of the door panel). Once the clips are pulled, pull the panel upward to remove it from the door.
Install in reverse.

If you are sure you have a key off battery drain, what you need to do is connect an ammeter to the negative side of the battery(disconnect the negative battery cable and connect one side of the ammeter to the battery terminal and one side to the and one side to the battery cable) note the reading and start pulling fuses one at a time making sure to put them back in their proper slot when the reading an the ammeter goes down to normal the short will be on the circuit of the fuse you have pulled if any part of these instructions is too difficult have the problem checked by a dealer

As you see in the first illustration. you can use your key to pry open the cover. It may or it may not contain the fuse locator card.
