Well this group has really helped in the past so i hope it can do it again.
Here is my situation. My 02 jetta has an issue where if it sits overnight, when you go to start it in the moring the battery is dead. I have made sure there is no lights on (trunk, door, etc.) that could be draining it. I recently purchased a new battery 6 months ago so i thought it could be a bad battery, replaced that and it lasted for three days before it too went dead. I went to autozone and advance auto and had them both do a electrical diag. Both came up with the alternator, starter and battery are good. There was also no vampire draw (hard to believe on that one). Once the car is started you can drive all day and it will start after being shut off. This only happens when it sits overnight (10 hrs). The only thing I have recently done with this car is to fix the electric lock in the rear door and to extent the key fob range (procedure on here) but that was months ago. I do not even know where to begin on this one. Has anybody had this problem before?
