  1. M3 Red Battery Light

    General E46 Forum
    Hi everyone, Was taking my 05 M3 vert out for a drive today. Wouldn't say I was driving super aggressively but wasn't a stroll around the park either. Oil temp was about 210. I accelerated fairly hard, almost to redline, and all of a sudden the red battery light turned on solid. Immediately...

  3. Help me narrow these issues down please

    General E46 Forum
    So I have a 2003 325i. It ran very well until the last few months when it began having small intermittent issues that are now happening much more frequently. Occasionally I lose all power and it feels as the engine is gonna stall. Its usually after putting a heavy load on the engine ( large hill...
  4. Shop Is Closed and I Need Advice

    General E46 Forum
    A little bit of a story: I was driving home from chipotle and noticed that my battery light had come on. I thought this might be from my alternator, as I had been hearing a weird sound coming from the engine that would point to that. Then, I looked and my temp gauge was all the way in the red...
  5. Battery Light - On after belt break

    General E46 Forum
    Hi everyone. I'm hoping to get some advice as my issue seems extremely coincidental. Last week my water pump pulley snapped and tore my serpentine belt to shreds. Of course the battery light immediately came on and the power steering froze up. I replaced the pulley and belt and all seemed to...
  6. Bad Alternator?

    General E46 Forum
    A question about an e46 M3 battery light. The battery light came on a week ago. I went home and checked the battery (12 months old, from BMW) and the voltage was fine. I then ran the diagnostic test I found here ( https://www.youtube.com/watch?v=svLl2geYxJg ). And it was showing only about...

  8. Battery light caused by oil level sensor blowing fuse 30

    DIY: Do It Yourself
    My red battery light was on the past few weeks even though the voltages were fine. It turns out it was caused by a bad oil level sensor that was blowing fuse 30. I've been doing a lot of research the past few weeks and I didn't see many stories quite like mine, so I thought I'd share: What...

  12. How long can I drive with a failing alternator?

    General E46 Forum
    For past few days the battery light comes on sometimes so I bought a new battery. Car has trouble starting after a day so I assume it's the alt failing. Ran OBC volt test and found 12V when car is off, and 13.1 when it's running. Does this mean the alternator is still somewhat charging the...

    I have had the battery light go on and off intermittently after I had the battery and alternator replaced. I ran the code scanner and got a BSD error...
