I posted a note earlier about a new battery for my 2000 Passat. I was thinking Sears where I've gotten many batteries before, but called my dealer to ask them. They tell me that there is "reprogramming" that needs to be done for a new battery. I confirmed with this another dealer. They said beyond the radio, there' may also be a need to reprogram the throttle body. With the cold snap here, they are both booked up until next week. The first dealer said I could put in a VW battery and sometimes the reprogramming isn't necessary or "heals itself". The worst he says is that the car might run a little rough and that I'd then need to bring it in for reprogramming.
Can anyone shed light on this?
