To echo what Ed said, start here for diagnosis:
- How to test a BMW E39 battery & alternator (1)

CUT-AND-PASTE TEACH-to-FISH RESPONSE FOR classic no information threads:
Sample information:
  • Mein auto: 2002 BMW 525i/M54 auto
  • List the DTCs found (e.g., P00m, P00n)
  • Also list the one-line description of those DTCs (don't force us look it up for you!)
  • Explain which debugging steps you followed (they all have 'em)
  • Explain your debugging test results
Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
