2003VW

A friend of mine told me that if the battery goes totally dead or is disconnected on my 2003 Jetta TDI that the program in the computer will be lost and need to be reflashed at a dealer. My battery is getting weak and I need to replace it and don't want to mess any thing up.
Can any one clarify this? I have searched this forum but couldn't find any info related to dead batteries and the computer.
