Good evening, I bought a used BMW 118d (E81) a good 9 months ago. Unfortunately I did not consider that I mostly drive short distance… – 3/4 times a week 3-7 kilometers per track. – irregularly about every two months 40km or more. The car is standing outside and just during the last rather mild winter, it hurt my soul when I started the engine.. Now the car has its 100tkm down and the battery is over and must be replaced (and the Li chtmaschine maybe also – tomorrow I get news from the workshop) I have actually already thought about selling the car again and buying a gasoline of the same model. However, the effort and the additional costs speak against it. What do you say about it? Now I have read about such an electric engine preheating. Should I then put extra power outside and always connect the car to it?
