The other night it was cold…-17°. In the morning at 7.30 am I want to go. The thing doesn’t start. The battery spins well through but no noise which sounded like fuel ignition or something like that. After three attempts I gave up. I told myself, …well, I drive just tomorrow…… The next day around the same time it was about -5°. The car jumped and I started but check engine lit up and didn’t go out even after 5 km. So I called the workshop from the car and asked t what I should do?. But they answered quite coolly, …..the lamp will go out again drive again a little…… So after 20 km the lamp was off and I thought….specialist is just professional…they saved me the ride into the workshop. Today I want to go again. Tomorrow -12°. The thing goes well, does not jump again. Obviously the supply of this does not work. What can it be? What should I do? The car is a Saab 9-3 tid Built 2005. In the The first battery…but that can’t really be true? Now you have a Swedes car, but thinks it’s hardy …….. Isenhagen
