Default How do you reset computer after dead battery

I'm fighting an intermittent electrical problem that kills my battery. I've replaced battery, alternator, driver door lock switch, gas door switch (didn't think it was the problem but it fell apart in my hand when I took the door panel off - took that as a hint). Thought I had it but one week later - dead battery again. Last time it was so dead that the computer lost its mind. I had it towed ($65) to the dealer and paid $94 to have the computer reprogrammed. It's with my daughter at college and I'm driving up tomorrow to get it. IF the computer is dead again, is there a way to reset it so I can crank it up and drive home or is a trip to a NC dealer the only way to reprogram it?

There is a power drain somewhere that needs to be traced out. What year is the car? What do you mean that the "computer lost its mind"?

Where in NC? There are a lot of great independent shops here that can help you out for much cheaper than the dealer.

According to what I was told, the computer lost its programming. It's a 98. She would fire up and immediately shut down. Every time. I went to NC and picked it up yesterday and mercifully, it cranked after I jumped it off. This weekend I'm going to start pulling fuses and see if I can track down the drain. Still wondering if a Vag Com would reset the computer in case it does the same thing again. Oh yeah, she's back in Georgia again - Macon area.

I've never heard of this before. VAG-COM might be able to help, but again, its not an issue that I've heard of before.

Where is your daughter at school? I'm currently at NC State

Thumbs up battery drain

Hi...just FYI...the computer does funky things when the battery voltage is low....the voltage draw you have is creating the dubster to omit bad vibes to the computer...you want to charge the battery fully and THEN see if this corrects the computer problem (which I feel it will)...THEN commence to wig out the voltage draw that keeps killing your battery....good luck...and be kind to that little beetle !!

She's at UNCG. She's a music major and sure did look cute in the bug. But the bug belongs to Daddy now as I got her a Honda that I could count on to crank. Thanks for the info. I suspect my issue has something to do with the locks at it seems to only go dead when the doors are locked. But, who knows. As I've read on the forum, pull the fuses one at a time...
