I have a 2010 Passat Komfort wagon that has a parasitic battery drain caused by locking the driver side door locks. Other features that set off the drain are using any or all of the following: the radio and aux outlet, rear defroster, fresh air circulation. Whatever is causing the drain resets after I jump the car and drive for awhile. I have the best mechanics working on and maintaining the car and even they are stumped. I’ve seen some YouTube videos where this problem has occurred on VW Jettas but nothing on Passats. Has anyone else encountered this problem and found the cause? Thanks.
