Moin to the country, I have been the owner of my dream car for half a year: V70 I, EZ 2000, 2.5 Ltr. with 140hp, automatic The car is in an absolute optical top state inside (with the exception of the door panels) and outside, and with very good equipment. It is a former natural gas car, temporarily converted to car gas (Prins). Now to my problem. The car is moved very little and mostly on short distances; in the dark season almost always with light, seat heating, blow, heated rear window etc. Now it has happened several times that the battery was completely empty. I had it tested in 2 workshops, it is in very good condition. Therefore, it is probably not on the battery. I still have to point out that I am not a screwdriver and can hardly fix the problem myself. I would like to limit the problem however, the possible troubleshooting in the electronics could become very expensive. lfen? Is that quite normal that the battery often discharges completely due to low usage in the season? Or is that a mistake in the electronics or elsewhere? I thank you in advance for your help!
