battery drain

  1. X5 E70 (2007 - 2013)
    Hello, so I have a 2008 X5 and have taken good care of it and done many repairs since I bought it 4 years ago. This spring while sitting parked with the car on for about 30 minutes all of the warning lights came on in the car. I turned it off and let it rest after a while I turned it back on and...
  2. X3 E83 (2004 - 2010)
    Upon investigating a parasitic battery drain issue today I found out that the drain went away after removing the sunroof fuse. Does anyone have any experience on what exactly in the sunroof causes the drain? I found an old post by someone having the same issue, and they said that the replacing...
  3. E60 / E61 (2004 - 2010)
    Hi there. Long time lurker, first time poster. I have a question regarding the Fuel Pump relay system and associated codes for an E60 w/ 4.8l engine: A few weeks ago during a recent cold snap, I needed to jump start my 550. I had the car on a charger for an hour or so and when I attempted to...
  4. E46 (1999 - 2006)
    My '02 e46 was imported from Japan and it had infamous infrared key which only works from couple meters. So i did retrofit of radio frequency key and changed antenna module as mine did not had radio frequency receiver for key. I followed instruction on the forums and connected 2 wires from new...
  5. X3 E83 (2004 - 2010)
    I've got a problem with my 2005 E83 3.0. a few days ago the driver side power mirror (non folding) began moving all the way to one side as soon as the memory triggered it, and the motor keeps running, even with the key off. It doesn't respond to the controls. I can stop it by pulling fuse 57...
  6. X3 E83 (2004 - 2010)
    I researched a lot of the forums for this type of problem and none that I could find included the fix I found on my car. History: Car Battery would drain even while parked. At first only a bit over long hours parked but eventually a faster drain (within about 15 minutes). 1st I began by...
  7. E60 / E61 (2004 - 2010)
    I have a 2006 530xi, the battery is being drained when the car should be in sleep mode. I determined that the drain was coming from the ignition system. I'm living with the problem by unplugging the appropriate fuse every night to stop the drain (7 in glove box). Where do I start with trying...
  8. E39 (1997 - 2003)
    Hello all, I have been putting up with a parasitic battery drain issue in my 540i (year 2000) for a couple of weeks now, and am ready to do something about it. Over this time I have been researching the issue and gathering the correct knowledge to proceed. I do however, have many questions...
  9. E60 / E61 (2004 - 2010)
    The battery in my 2004 530i has died multiple times over the past two months, this last time once I jumped it and started the engine the wiper blades turned on by themselves and won't turn off now. As well as when I hit unlock on the key only the back doors would unlock/lock. Anyone know what...
  10. E90/E91/E92/E93 (2006 - 2013)
    Ok, so I have a terrible parasitic drain on my 335i. New battery, Alt checks out fine (pushing 14.2-4 volts but seems to drop when rpm goes up instead of raising). I have lost two areas (ECU's?) on my dashboard when I toggle the stalk on the steering wheel- I am missing both of the key fob...
  11. X3 E83 (2004 - 2010)
    Hello all, I need some serious help trying to figure out what is exactly wrong with my X3 and how to fix the problem. I will try and make long story short. The car has moved from a cold climate to a warm climate. When the car was exposed to cold temperatures in the previous years, the battery...
  12. X6 E71 / E72 (2008 - 2014)
    I posted this before too. Time and date keeps resetting on my vehicle, I don't know when battery was changed and don't know, if dashcam with parking mode drained it beyond repair. I charged for couple of days with Ctek charger it goes to 7th stage and once I unlock and lock doors it drops back...
  13. 7 Series - E38 (1995 - 2001)
    On halloween last year, the problems started. First the battery would just randomly die. It would jump with no problem. I went to Tires Plus (I know, big mistake) and they gave me a new battery. I went home with no problems and the next morning the battery was dead again. Now, Tires Plus is...
  14. X5 E70 (2007 - 2013)
    Hi All, I bought my 2010 X5d with Premium, Technology and Cold Weather package as a CPO with 35k miles on it back in Jan 2013 for a very reasonable $36k. I now have 72k miles on the odometer. This is my first BMW after only ever having owned Japanese/Korean cars. I've had the car for 3 years...
  15. X5 E53 (1999 - 2006)
    Hello All, What does it mean when the battery symbol takes a long time to go out after I start the car? Yesterday my car wouldn't start, and the battery was charged. I had it checked, and was told it was fine. Today the car started, but the battery symbol stayed on much longer than it usually...
  16. E90/E91/E92/E93 (2006 - 2013)
    Anyone remember the threads some time ago about the ghostly battery drain issue on BMW's? All sorts of solutions were offered. Well, my 328i had it back then, took it in to the dealer, would not duplicate, issue seemed to go away. Now it is back. It seems like the car does not shut down as...
  17. 7 Series - E65 / E66 (2002 - 2008)
    Hi, I've been lurking on this forum for a while, and got lots of good info from the experts. Now I have a problem that I can't find anything about. Some background: 2008 750i, ~104K. I had the starting problem where you press the button and nothing happens. Replaced the IVM as many have...
  18. E90/E91/E92/E93 (2006 - 2013)
    Recently, my battery died in my car after a quick acceleration to pass a car on the interstate. Took it to my indy mechanic for the repair. Was told that the alternator was bad and paid to have it repaired. When picking up the car, I was told that the battery could be bad due to the multiple...
  19. E60 / E61 (2004 - 2010)
    I had a issue with my alarm going off for no reason, went to unlock the car with remote and nothing worked. Car was completely without power. it had rained and after many searches and calls I found that I needed to dry the battery area and all went back to normal. it just happened again a few...
