Hi, in my city temp is around -20 degree and my a4 fails to start, though if I leave it for 7-8hrs then it starts on its own. I also get this error message "Fuse" on dashboard and dashboard lights don't turn on, when i took to local garage and they couldn't find any problem, he said he did a reset of computer and nothing else but he couldn't figure out why was the "Fuse" message coming. Now today again it failed to start with same message and same symptoms?
