How long has your 2008 BMW 335xi had this problem?
RepairPal Certified shops can diagnose and repair your 2008 BMW 335xi. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Let’s evaluate the situation - this occurred immediately following battery replacement - no battery power at all now - - the new battery is defective - - the cables are not making sufficient contact - - you inadvertently touched the cables to the wrong battery terminals resulting in reversed polarity which has blown the MAIN fuse.
Good luck!
