    General E46 Forum
    My alternator just went out on me today and I'm getin ready to start pulling it off but I need to order the new one so it's here by Saturday. They asked me whether or not it was a Bosch or Valeo, is there a quick easy way to tell which one I need? If it helps my car is a 2000 323i. Please help...
