Hey everybody first time poster so sorry if I'm posting in the wrong area. I have a 2012 jetta tdi with a parasitic draw of about 3.5 amps. I just purchased the car from a used non VW dealer as is. The car had no issues but I decided to try out the VCDS trial software with an amazon China cable i had from another car. No setting were messed with just checked the trans temp as I was planning to do a DSG fluid change. The car has a newly purchased battery of 12.6 volts goes dead in 4-6 hours. The battery has been tested and all cells are good. I've used the tsb method and tested every fuse for voltage drop and could not find the culprit. To be on the safe side I removed factory fender amp and raido. I've hit a wall on where to go next and really dont want to bring to local dealer and raked over the coals. Thanks for input!
