I have a 2001 VW Jetta V6. For s about two years my car has been draining batteries every 8 or nine months.VW says the voltage draw with the car off should be between 40 to 50 mila amps. My mechanics say my car is drawing 50, and have thrown up their hands, and told me I have batteries for life. Dosen't help when your stuck somewhere with a dead battery. Went away for seven days, 3 month old battery DEAD!
