My wife has an '06 NBC that has had its share of electrical issues. one of them has been the battery. Back in 2010, we had a problem with the battery going dead after a few days even though it appeared to be holding a full charge under load and according to the dealer the battery was fine but there was a short in the radio causing the problem. They wanted $700 to replace the radio. $700 for a radio! no way. So I took it across the street to an auto audio place and had an aftermarket radio installed that had a lot better sound and features than the stock radio. Anyway, that did not fix the problem. So I took the bug over to an Auto electric service shop and the first thing he did was was replace the battery...Which of course fixed the entire problem. The Beetle did the same thing again this past week, showing a full charge, even under load after jumping from my other car. Battery dead agaiin in 2 days. Just replaced the battery and all is well. So just wanted to let you know. If your VW is not starting and it is showing a full charge, it is still most likely that you need a new battery.
