I am planning to change out my battery myself on my 2003 Jetta TDI in the near future. The changeout is going to be done for preventative maintenance (before the battery fails). I do not want to be stranded somewhere. I did not know until today that you need to keep voltage on the computer during the changeout process. I have located an inexpensive 9 volt computer memory saver that I can purchase.
Questions:
1. What happens to the computer if power is totally lost? Will the car not start at all with the new battery?
2. How many other makes/models of vehicles require a computer memory saver hookup for a battery changeout? I never had any known problems with my battery changeouts of my previous vehicles (1993 Mercury Sable & 1995 Chevrolet P/U).
Thanks in Advance.
